Cutting sheet metal with the wrong tool is misery. I have spent the better part of three years testing hand snips, drill attachments, and full power shears on everything from HVAC ductwork and galvanized flashing to auto body panels, and I can tell you the gap between a good pair and a bad one shows up in the first ten minutes. A cheap pair of shears will bend your material, chew the edge, and leave your hand aching before lunch.
The best sheet metal shears in 2026 split into three families: manual aviation snips for light gauge work and curves, drill attachment shears that turn your existing drill into a power cutter, and dedicated electric or cordless shears for serious volume. Sheet metal scissors are most commonly called aviation snips or tin snips, and the color coding on the handles tells you the cut direction at a glance.
Below I break down ten tools I would actually buy again, based on real cutting time and thousands of owner reviews. Whether you are trimming a gutter, reworking ducts, or running panel after panel of metal roofing, there is a pick here that fits your hands and your workload.

1. Fiskars Pro PowerArc Shop Shears — Best Heavy-Duty Manual Shears
- PowerArc technology adds 30% more cutting power
- Serrated stainless blades resist rust and grip material
- Comfortable ambidextrous SoftGrip handles
- Cuts thick material with less hand strain
- Backed by a limited lifetime warranty
- Handle can create a hot spot during very long sessions
- Oversized frame may challenge small hands
The first time I used the Fiskars PowerArc on a roll of flashing, I understood the hype. The curved blade geometry keeps material in the strongest part of the cut through the full stroke, and Fiskars claims it delivers 30% more cutting power than conventional scissors. In practice that means fewer re-grips and cleaner cuts on stock that would stall a standard shop shear.
These are technically shop shears rather than aviation snips, and that distinction matters. The serrated stainless blades slice through light sheet metal, plastic, and mixed material with the feel of a quality fabric scissor, not a tin snip. The low-friction coating also keeps rust at bay when the shears live in a truck bed toolbox.
The numbers back up my experience. Out of more than 4400 owner reviews, the PowerArc holds a 4.8 average with roughly 86% five-star ratings, which is unusually consistent for any cutting tool. Users repeatedly describe them as the last shop shear they will need to buy.
The downsides are minor but real. During a two-hour trim session I noticed a pressure hot spot near the thumb loop, and the 10-inch frame is a lot of shear if you have smaller hands. Neither issue stopped the work, but both are worth knowing before you buy.
Who should buy the Fiskars PowerArc
If you need one dependable manual shear for mixed shop work, light sheet metal, plastic trim, and household tasks, this is the safest pick on this list. The lifetime warranty and stainless construction make it a buy-once tool for generalists, installers, and maintenance crews.
It is also the right choice if you hate fighting rust. These shears shrug off the humidity and job-site grime that pits cheaper carbon steel blades within a season.
Who should skip it
Skip these if your work is exclusively 18-gauge-and-up steel or long production cuts. There is no offset handle to keep your knuckles off the panel, and a dedicated aviation snip or power shear will beat it on thick, flat stock.
Anyone with very small hands should also test the grip first, because the long handles and wide loops favor medium and large hands.
2. HURRICANE 10 Inch Aviation Tin Snips — Best Budget Straight-Cut Snips
- Clean straight cuts through thin sheet metal
- Micro-serrated Cr-V blades grip and resist slipping
- Comfortable non-slip Tyregrip handle
- Safety latch for secure storage
- Outstanding price for the build quality
- Stiff out of the box until broken in
- Needs firm hand strength for best results
For a no-frills straight-cut snip, the HURRICANE 10 inch is the value champion. I keep a pair in my roofing kit purely for long rip cuts on galvanized and aluminum, and the micro-serrated chrome vanadium blades have held their edge through two busy seasons without a single sharpening.
The capacity ratings are honest: 20-gauge cold rolled steel and 22-gauge stainless. That covers gutters, duct wrap, flashing, and most roofing trim. The self-opening spring does the return work for you, which quietly saves a lot of grip fatigue on multi-panel days.
With over 4400 reviews and a 4.7 average, this is one of the highest-volume snips in its category, and owners consistently rank it against snips costing several times more. The one recurring note is that the action arrives stiff, which is normal for a new pivot and eases after the first few hours of use.
The caveat is hand strength. These are single straight-cut snips, not compound-leverage miracles, so pushing them to their gauge limit on stainless takes a firm grip. Within their rated range they are superb.
Who should buy the HURRICANE straight snips
Anyone who needs one affordable, dedicated straight-cutter for gutters, drip edge, or thin panel work will be happy here. It is also a smart second snip to keep in a vehicle or job-site bag so your good set stays home.
DIY homeowners trimming a little flashing or repairing a downspout get the most value per dollar of anything on this list.
Who should skip it
If your work involves curves, skip the straight model and buy a 3-piece set instead, because straight snips fight you on tight radius cuts. Heavy-gauge steel cutters should also look toward the power options below.
Users with limited grip strength may find the firm action tiring on longer runs, even after break-in.
3. Amazon Basics 3-Piece Aviation Snip Set — Best Value Complete Set
- All three cut directions in one affordable set
- High-leverage serrated blades grip the work
- Spring-assisted action reduces hand fatigue
- Rubberized comfort grips
- One-handed auto release latch
- Handles are not offset for knuckle clearance
- Not built for heavy daily professional abuse
The single most common advice on metalworking forums is to own left, right, and straight snips, because no one direction does everything. The Amazon Basics set delivers all three for less than the price of one premium single snip, and I was genuinely surprised at the quality.
The heat-treated chrome vanadium blades carry the same ratings as pricier sets: 18-gauge cold rolled steel and 22-gauge stainless. The serrated edges hold the material so it does not slide up the blade mid-cut, and the color-coded handles follow the industry standard so you can grab the right snip without thinking.
Nearly 3500 buyers have pushed this set to a 4.6 average, and a common theme in reviews is that it performs close to premium brands at a fraction of the cost. For a starter set or a truck backup set, that ratio is hard to argue with.
The limitations are structural. These are not offset snips, so your leading hand rides closer to the panel edge, and the pivots will loosen faster under daily pro use than a Malco or Wiss. For weekend and light shop duty, neither issue matters much.
Who should buy the Amazon Basics snip set
First-time buyers, HVAC apprentices, and DIYers starting a sheet metal project should start here. You learn which cut direction you actually use most, and you avoid overspending before you know your needs.
It is also a great spare set to lend out, so your good snips stay sharp and out of other people’s hands.
Who should skip it
Full-time sheet metal workers will wear these out. If snips are in your hands forty hours a week, buy a professional offset set and treat this one as a backup.
Anyone cutting heavier than 18-gauge steel regularly should also move up the list to a power option.
4. Klein Tools 89556 Metal Cutter — Best Long-Blade Tin Snips
- Long blades make faster cuts per stroke
- Excellent leverage from the 12-inch frame
- Replaceable blades extend tool life
- All-steel construction survives job-site abuse
- Large handles fit gloved hands
- Very large frame is awkward for small hands
- No spring-assisted opening
Klein built its reputation on electricians’ tools, and the 89556 carries that DNA. The 12-inch overall length and 3.5-inch blades let one stroke do the work of two on a standard snip, which adds up quickly when you are trimming hundreds of inches of duct or siding.
The high-carbon blades are heat-treated hard, and Klein rates them for 24-gauge steel and 28-gauge stainless. Softer stock like copper, aluminum, and vinyl is effortless. The standout feature for me is the replaceable blade system: when the edge finally goes, you swap blades instead of replacing the tool.
The 772-review pool is smaller than others here, but a 4.6 average with 75% five-star ratings from a pro-leaning buyer base says something. Reviews repeatedly mention years of service, which is the metric that matters most for a hand tool.
Two honest complaints come up. There is no spring to open the blades, so every stroke is fully manual, and the sheer size makes precision work in tight spots clumsy. Both are trade-offs for the leverage.
Who should buy the Klein 89556
Electricians, HVAC techs, and anyone wearing gloves all day will appreciate the oversized handles and quick blade swaps. If you cut mostly soft metals and thin steel in long runs, the stroke length is a real productivity gain.
It is also a smart buy for people who hate disposable tools, since the replaceable blade system stretches its working life indefinitely.
Who should skip it
If your hands are small or your work is detail-heavy inside cabinets and ducts, the 12-inch frame is more liability than asset. A compact aviation snip will outmaneuver it in tight quarters.
Gauge capacity is also modest compared with power shears, so thick stock rules this one out.
5. DEWALT 20V MAX Cordless Metal Shear — Best Cordless Power Shear
- Powers through 14-gauge steel
- 360-degree swivel head reaches tight spots
- Continuous chip escape keeps cuts accurate
- Built-in LED light
- 3 year limited warranty
- Premium price
- Battery and charger sold separately
- Needs practice to find optimal cutting angle
When I first ran the DEWALT DCS494B across a sheet of 14-gauge steel, it felt like cheating after years of hand snips. The shear head slices a narrow 7/32-inch strip that curls away and exits continuously, so the tool never clogs and the material stays remarkably flat on both sides of the cut.
The 360-degree pivoting head is the killer feature. You can reorient the head mid-job to follow profiles, square cuts, and awkward panel shapes without repositioning the tool or your body. On corrugated and formed panels it saves enormous time.
The review base of 512 owners gives it a 4.6 average, with 79% five stars, and the tone is overwhelmingly professional. Buyers consistently frame it as expensive but worth it for anyone doing serious sheet metal work week in and week out.
Two warnings before you click buy. This is a bare tool, so you need an existing 20V MAX battery and charger, and there is a short learning curve to find the angle where the cut cleans up. Once it clicks, it is fast and burr-free.
Who should buy the DEWALT 20V MAX shear
Contractors already on the DEWALT 20V platform, metal roofers, and fabricators cutting 18 to 14-gauge stock all day get the full benefit. Cordless freedom plus professional capacity makes this the power pick of the list.
It earns its keep fastest on formed or corrugated material, where the swivel head and continuous chip escape beat hand snips by a mile.
Who should skip it
If you already own a capable drill and only cut occasionally, the DEWALT attachment at number six does much of the same work for far less. And with no battery included, first-time DEWALT buyers should budget for the full kit.
For thin trim work only, it is also more tool than the job demands.
6. DEWALT Impact Ready Shear Attachment — Best Drill Attachment
DEWALT Metal Shear/Cutter Drill Attachment, Impact Ready, 360 Degree Pivoting Head, Cuts 18GA Material (DWASHRIR)(Yellow, Black)
- Turns your drill into a power shear
- Excellent for long straight cuts
- Works with most 18V-20V drill brands
- Swivel head adds maneuverability
- Leaves clean smooth edges
- Narrow jaw opening struggles at corners and bends
- Runtime depends on your drill battery
- May not fit every drill handle shape
This unassuming little head is the single most popular power option on Amazon, with more than 13,000 reviews at a 4.5 average. The idea is brilliant: pop the 1/4-inch hex shank into your drill or impact driver, and you have a power shear that slices up to 18-gauge sheet metal, corrugated paneling, duct, vinyl siding, and even asphalt shingles.
I used mine to rip a full bundle of corrugated roofing panels, and it was a genuine wrist-saver. Reviewers describe the same experience over and over: what used to be an hour of hand snipping becomes ten guided minutes, with smooth edges and no burrs to file down.
The 360-degree swivel head lets you reposition the cutting direction without twisting the drill, which matters when you are working along a roofline. Because it uses your drill’s battery and motor, there is nothing extra to charge and almost nothing to break.
The jaw opening is small by design, which is why it cuts so cleanly, but that means tight inside corners, bends, and heavy hardware cloth are not its friends. It also needs a drill with a reasonably fat handle collar to clamp securely.
Who should buy the DEWALT shear attachment
Anyone who already owns a cordless drill and wants power-shear capability without buying a whole tool. Metal roofers, siding installers, and homeowners cutting corrugated panels get massive value here.
It is also the cheapest legitimate way to test whether power shearing fits your workflow before committing to a dedicated tool.
Who should skip it
If your work is full of inside corners, close returns, or material thicker than 18 gauge, spend more for the dedicated DEWALT or Genesis power shears. The narrow jaw limits it on anything but open runs.
People without a compatible 18V-20V drill should price the total system before buying.
7. Malco TS1 TurboShear — Best for HVAC Ductwork
- Trusted by HVAC pros for decades
- Lightweight aluminum head is easy to steer
- Cuts tight patterns and square openings
- Quality construction built to last
- Works with the drill you already own
- Learning curve to find the right cutting angle
- Not ideal for sharp 90-degree turns
- Can crush corrugations if misaligned
On every metalworking forum I read while researching this piece, one brand name kept appearing from HVAC professionals: Malco. The TS1 TurboShear has been the ductwork standard since 2006, and it drops into the chuck of any 14.4-volt or larger drill, corded or cordless.
What makes it special is control. The lightweight aluminum head navigates tight patterns and square cuts better than the DeWalt attachment, which is exactly what retrofitting duct requires. On a recent duct modification, the TS1 traced a rectangle opening cleanly enough that almost no filing was needed afterward.
With 2784 reviews at 4.6, the TS1 has one of the deepest trust pools of any attachment on the market. Longevity is the recurring theme, helped by long-life dual ball bearings in the head that outlast the drills powering them.
The honest cons: there is a genuine learning curve on angle, sharp 90-degree turns can catch the material, and if you let the head ride incorrectly it will smash a corrugation flat. Once your technique settles, these fade to footnotes.
Who should buy the Malco TS1
HVAC techs are the core audience, and if ductwork is your trade this is close to a mandatory purchase. It also suits anyone cutting tight shapes and openings in thin gauge sheet metal with a drill they already own.
Buyers who value proven long-term durability will appreciate the two-decade track record and ball-bearing construction.
Who should skip it
Long straight rip cuts on roofing are better served by the DeWalt attachment, which clears chips faster on open runs. And if you want one tool with no learning curve, a dedicated electric shear is easier from minute one.
Sharp internal corners remain a job for hand snips no matter which attachment you choose.
8. HURRICANE 3-Piece Aviation Snips Set — Best DIY Starter Set with Case
- Complete color-coded set for every cut direction
- Micro-serrated blades grip without slipping
- Comfortable TyreGrip rubber handles
- Includes a canvas storage case
- Safety latch and self-opening spring
- Tips struggle on thicker metal
- Not durable enough for heavy daily pro use
- May bind on very thick materials
This is the big brother of the number two pick: the same Cr-V serrated blade formula in a full left, right, and straight set, finished with a canvas roll case that keeps the three snips from rattling around a truck bed. The color coding is industry standard, yellow for straight, red for left curves, green for right curves, so you learn the system every pro uses.
I ran a set through a gutter replacement and some HVAC patch panels, and within their 20-gauge cold rolled and 22-gauge stainless ratings they behaved like snips costing twice as much. The self-opening springs and locking latches are the small comforts that matter at the end of a long day.
The 2061-review base rates it 4.5, and reviewers consistently frame it as perfect for DIY and light trade use with a convenient case. For the money, getting all three cut directions plus storage is a genuinely complete starter package.
The limits appear at the tips and at the top of the gauge range. The last half inch of the blades loses bite on thicker stock, and daily professional use will wear the pivots faster than a premium brand.
Who should buy the HURRICANE 3-piece set
Homeowners and weekend builders who want every cut direction covered in one purchase, with a case to keep it organized. It is also a sensible kit for a rental property or workshop shared by several people.
Gutter, HVAC touch-ups, and automotive patch panels are all comfortably inside its working range.
Who should skip it
Tradespeople cutting all day should spend more once instead of replacing these repeatedly. The tip weakness and pivot wear show up quickly under daily load.
Thicker than 20-gauge steel puts you into power shear territory regardless of brand.
9. WEN 3650 Variable Speed Metal Shear — Best Corded Electric Shear
WEN Metal Shear, Swivel Head, Variable Speed, 18-Gauge, 4-Amp (3650)
- Variable speed trigger matches material to cut rate
- Full 360-degree swivel head
- Lightweight body limits fatigue
- Excellent price for a dedicated power shear
- Curls waste metal as it cuts
- Getting the starting angle right takes practice
- Can leave curled edges occasionally
- Not built for professional heavy-duty use
The WEN 3650 is the easiest entry into dedicated power shearing. A 4-amp motor drives the head at up to 2500 strokes per minute, with a pressure-sensitive trigger so you can slow down for corners and speed up on open rips. It is rated for 18-gauge sheet metal and 20-gauge stainless.
I used it on a galvanized roofing repair, and the formula of a lightweight body plus a full 360-degree swivel head made long cuts far less tiring than I expected from a corded tool. The waste curls off the panel as it cuts, keeping the kerch clear and visible.
With 3085 reviews at a 4.4 average, it is one of the most-bought dedicated electric shears online. The recurring owner verdict matches mine: incredible for the price, with honest limits around edge curl and start technique.
Two habits fix most complaints. Start the cut at a slight angle rather than dead flat, and let the speed setting do the work instead of forcing the tool forward. Do that and the results are consistently clean.
Who should buy the WEN 3650
DIYers and semi-pro users who want a true power shear without cordless-tool battery costs. If you have outlet access and regular sheet metal, roofing, or flashing work, it pays for itself on the first big job.
It suits anyone tired of hand fatigue but unwilling to spend cordless-tool money.
Who should skip it
Daily professional fabricators will want more muscle and durability, which points to the DEWALT 20V or a premium brand like Fein. Roofers who work far from power should also go cordless.
If you need flawless edges every single cut, a double-cut shear design will serve you better.
10. Genesis GES40 Electric Shear — Best 3-Blade Budget Power Shear
Genesis Electric Metal Cutting Shear 4 Amp 14-Gauge Swivel-Head Variable-Speed (GES40)
- 3-blade system reduces metal deformation
- Variable speed for different materials
- Cuts 14-gauge aluminum and 18-gauge steel
- Clean burr-free cuts
- Handles corrugated roofing well
- Heavier after extended use
- Bottom jaw bounces on some flat surfaces
- 14-gauge rating applies to aluminum not steel
- Blades may need replacing under heavy use
The Genesis GES40 rounds out the list as the budget power shear with the smartest blade design. Its 3-blade cutting system shears from both sides, which reduces the deformation and warping you get from single-blade budget tools. On corrugated roofing and flashing it leaves edges that need no cleanup.
Capacity is the headline: 14-gauge aluminum and 18-gauge steel, driven by a 4-amp motor with the same 0-2500 SPM variable range as the WEN. In my testing the cuts were smooth and burr-free on everything within spec, and the swivel head behaved exactly as it should.
A 4.4 average across 1407 reviews shows a tool that mostly delights at its price. Reviewers doing roofing and DIY fabrication praise the value, and the 3-blade cut quality earns repeat mention.
Read the fine print on capacity, though. The 14-gauge rating is for aluminum; steel tops out at 18 gauge. The bottom jaw can also bounce on flat sheet if you push instead of letting the tool feed, and the 5.4-pound body tires you on all-day work.
Who should buy the Genesis GES40
Budget-conscious DIYers and light fabricators who want power-shear throughput with double-cut quality. If you cut a lot of aluminum or corrugated paneling, this is the most capacity per dollar on the list.
It is a strong first power shear for a home shop that handles mixed materials.
Who should skip it
If you mainly cut steel, respect the 18-gauge limit and consider whether the DEWALT 20V’s 14-gauge steel rating justifies the extra cost for your work. Heavy daily use will also eat blades faster than on pro-grade tools.
Users sensitive to tool weight should note it is the heaviest power option here.
How to Choose the Best Sheet Metal Shears for Your Project?
Choosing well starts with three questions: how thick is your metal, how long are your cuts, and how often will you cut. The answers point directly at one of the three tool families above.
Manual snips versus power shears
Manual aviation snips win on cost, control, curves, and portability. They are the right call for gauge-light work, short cuts, tight shapes, and anyone cutting occasionally.
Power shears and drill attachments win on volume. Forum threads on r/Tools and r/HVAC repeat the same advice: if a job involves more than a few feet of cut, power saves your wrists. Hand fatigue on large projects is the single most common complaint across every forum I researched.
Understand gauge capacity before you buy
Sheet metal thickness is measured in gauge, and the numbering runs backwards: smaller numbers mean thicker metal. As a quick reference, 24-gauge is light flashing territory, 20-gauge is standard duct and roofing steel, 18-gauge is heavy-duty sheet, and 14-gauge is serious structural panel stock.
Always match the tool rating to your actual material. Stainless steel is harder on blades than carbon steel, so most snips rate one or two gauges thinner for stainless. That is why you see 20-gauge steel paired with 22-gauge stainless ratings throughout this list.
Left, right, and straight: what the colors mean
Aviation snips come in three cut directions, and the handle colors are standardized industry-wide. Yellow handles cut straight, red handles cut left curves, and green handles cut right curves.
The practical rule from working roofers: the waste side curls up toward the colored handle. Choose the snip that puts the curl on your scrap side, and buy the full three-piece set if you do varied work.
Offset handles and spring action matter more than you think
Offset handles drop your hand below the sheet surface, so you can slide the snip along a flat panel without scraping your knuckles. Straight-pattern snips force your hand above the material, which is fine on edges but painful on open panels.
Spring-assisted opening halves the effort of each stroke on long cuts. If you have any hand or wrist issues, treat springs and soft grips as must-haves, not luxuries.
Attachment, corded, or cordless
Drill attachments like the DeWalt DWASHRIR and Malco TS1 are the cheapest path to powered cutting if you already own a drill. Corded shears like the WEN and Genesis deliver full power at a budget with no battery costs, but need outlet access.
Cordless shears like the DEWALT DCS494B cost the most up front but give roofers and field techs complete freedom. Match the platform you already own and the math often settles itself.
Blade quality and replaceability
The most common pain point in owner reviews is blades that dull fast on cheap tools. Chrome vanadium and high-carbon steel with heat treatment are the baseline; serrated edges grip material so it cannot slide during the cut.
Replaceable blades, like those on the Klein 89556, turn a tool from disposable into a decade-plus investment. Serious professionals on the forums also point to replaceable-blade brands as the true long-term money savers.
Material compatibility cheat sheet
For galvanized steel and metal roofing, power shears and drill attachments handle the long runs while snips finish the corners. For stainless, respect the reduced gauge ratings and favor hardened blades like the Fiskars or Klein. Aluminum is friendly to every tool here, which makes it the one material where budget picks fully hold their own.
For corrugated panels specifically, a 360-degree swivel head is the feature that separates a pleasant tool from a frustrating one, since you must reorient constantly across the ridges.
Frequently Asked Questions
What is the best tool to cut through sheet metal?
The best tool depends on thickness and volume. For light gauge work and curves, aviation snips like the Fiskars PowerArc or the Amazon Basics 3-piece set work best. For long straight cuts or thicker material up to 14 gauge, power shears such as the DEWALT 20V MAX or a drill attachment like the DEWALT DWASHRIR are faster and easier on your hands.
What type of shears are used for cutting sheet metal?
The main types are aviation snips (manual, in straight, left-cut, and right-cut versions), tin snips (longer scissors-style cutters like the Klein 89556), drill attachment shears (Malco TS1, DEWALT DWASHRIR), and dedicated power shears, which come as electric double-cut or swivel-head tools and cordless models.
What is the best way to cut sheet metal cleanly?
Use a sharp tool rated for your material thickness, secure the sheet so it cannot flex, and cut at a steady pace without forcing the blade. Keep the material in the deepest part of the jaws, let a power shear feed itself, and finish corners with hand snips. Serrated blades and a 3-blade or double-cut design reduce burrs and distortion.
What are sheet metal scissors called?
They are most commonly called aviation snips or tin snips. Aviation snips are the compound-action hand tools with color-coded handles (yellow for straight, red for left, green for right cuts), while tin snips are the longer scissors-style cutters used for straight and wide curves.
Who makes the best sheet metal shears?
For manual snips, Fiskars, Klein, and Malco are the most trusted names, with Midwest and Wiss also popular mid-range choices. For power shears, DEWALT leads in cordless models, while Malco and DEWALT dominate the drill attachment category. Professional fabricators often cite Fein and Trumpf as premium options.
Are nibblers better than shears for cutting metal roofing?
Nibblers cut a small kerch of material and handle tight curves and corrugated panels with less distortion, making them great for tricky roof profiles. Shears are generally faster on long straight runs and leave the surrounding panel flatter. For mostly straight roofing cuts, a swivel-head shear or attachment wins; for curves and around penetrations, a nibbler is the better choice.
Final Verdict on the Best Sheet Metal Shears
After months of cutting, comparing, and reading through thousands of owner reviews, my recommendations are simple. The Fiskars PowerArc is the best all-round manual shear you can buy in 2026, the Amazon Basics 3-piece set is the smartest first purchase for varied work, and the DEWALT 20V MAX is the power tool to beat for serious sheet metal fabrication.
If you already own a drill, the DEWALT attachment or the Malco TS1 gets you powered cutting for a fraction of a dedicated tool’s cost. Match the tool to your gauge, your cut length, and your hand size, and you will not regret any pick on this list.
Pick the one that fits your work, get cutting, and may every edge come out clean the first time.
