Carve Clean 45° Drywall Edges That Actually Tape Flat — No Rasp, No Fuzz
You scored your sheets with a utility knife and the cuts came out ragged. The TrueEdge™ Chamfer Plane shaves a clean 45° bevel down every cut edge in one pass — so your tape sits flat, your mud goes on thin, and you're not back here in six months patching cracks.
Stop Fighting Ragged Drywall Edges That Won't Lay Flat
Knife-cut drywall edges come off jagged, fuzzy, and uneven. Try to tape over that and the seam telegraphs through your topcoat — or worse, cracks once the wall settles. A surform rasp helps, but you'll burn an hour on a single room and your wrist will hate you. There's a faster way.
➤ Dial It In Once, Run Every Edge Identical: Adjustable 2–9mm chamfer depth (~0.08–0.35"), plus a 0–12mm flat-plane mode for shaving high spots. Set the knob, lock it down, and every pass cuts the same — no babysitting the angle.
➤ Grips the Board, Not Your Hand: The aluminum body and non-slip thumb pad ride flush against the edge so the blade doesn't dive, skip, or bind up. You can run a full sheet without your wrist locking up halfway through.
➤ Swap Blades in Under 30 Seconds: Loosen the knob, lift the clamp, drop in a new blade, tighten. 10 spares come in the box — enough sharp edges to outlast a basement, a garage conversion, and a spare bedroom.
Two Blades, One Aluminum Body, Zero Tear-Out
Inside the body sit two cutting positions: a 45° angled blade for chamfering cut edges, and a flat blade for shaving high spots or planing material flush. Loosen the thumb knob, swap which blade is exposed, lock it back down — under a minute, no extra tools.
The non-slip thumb pad is what most cheap planes get wrong and this one gets right. It keeps the body riding flat on the edge of the sheet so the blade doesn't dive into the gypsum or tear up the paper. The difference shows up the first time you try to tape over your work.
Why DIYers Stopped Reaching for the Drywall Rasp
Word spreads fast on basement-finish forums. "Did three rooms last weekend, the cuts came out cleaner than the factory tapered edges. Wish I'd had this on my last wall — I would've saved a whole afternoon of rasping." — Mike R., Ohio. Same story over and over: ragged seams turn into clean chamfers, tape lays flat the first time, mud goes on thin.
Cleaner Edges, Faster Walls, Less Sanding
✓ Tape Sits Flat the First Time: A consistent 45° chamfer gives joint compound something to grab — no humps under the tape, no hairline cracks coming back at you next year.
✓ Works on More Than Just Drywall: Gypsum board, MDF, cork sheet, acoustic panel — same plane, same blade, same clean edge. One tool covers most of what's stacked in your garage.
✓ Quieter Than a Power Tool, Faster Than a Rasp: Manual control means no dust cloud, no extension cord, no shredded paper edge. Just a clean curl of gypsum coming off the blade.
Three Steps from Box to First Cut
Step 1: Loosen the thumb knob and lift off the blade clamp — the included tools handle it in seconds.
Step 2: Drop in a fresh blade (or rotate the existing one), set your chamfer depth, then tighten the knob back down.
Step 3: Hook the body over the cut edge, pull the plane along the sheet, and watch a clean 45° chamfer roll off in a single pass.

Got Questions? Real Answers Below.
Will it work on standard ½" and ⅝" drywall?
Yes. The 0–12mm flat range and 2–9mm chamfer cover both ½" (12.7mm) and ⅝" (15.9mm) gypsum board with room to spare. Set the depth once and pull.
Does it actually clean up a fuzzy knife-cut edge, or just nick it?
It carves a fresh 45° face on the cut, paper and all. Tear-out from your utility knife gets shaved away in the same pass — no rasping after.
How long do the blades last?
A single blade typically handles 15–25 sheets of drywall before it dulls — you've got 10 spares in the box, so you're covered through most projects.
Can a beginner get a clean cut on the first try?
Yes. Set the depth, hook it on the edge, pull. The thumb pad keeps the body flat — there's no technique to learn, no angle to babysit.
Any safety steps I should know?
Wear safety glasses (gypsum dust will fly), keep the tool out of kids' hands, and store it dry. The blades are sharp — handle them like utility blades.
