A bevel can look nearly finished at 220 grit, then reveal deep 60-grit scratches after etching, stonewashing, or applying a satin finish. That is why the question is not simply what grit progression for knife bevels looks good on paper. The right sequence must remove the scratches from the belt before it without wasting belts, overheating the edge, or rounding off crisp plunge lines.
For most knife makers running a 2x72, the dependable answer is to start as coarse as the job requires, then make controlled jumps: 36 or 60, 120, 220, and 400 grit. Add 600 grit only when the finish calls for it. That progression is not a rule carved in steel, but it is a productive baseline that works across stock-removal blades, forged blades, and common carbon or stainless steels.
What Grit Progression for Knife Bevels Should You Use?
Start with the condition of the blade, not the finish you want. A blade that needs its profile corrected, flats cleaned up, or bevels established quickly may need a 36- or 60-grit ceramic belt. A blade that is already flat, heat treated, and ready for final bevel work may begin at 120 grit. Starting too fine is slow. Starting too coarse when the blade does not need it creates scratch depth that takes extra time to erase.
A practical working progression looks like this:
| Job | Productive grit sequence | What it accomplishes |
| --- | --- | --- |
| Rough stock removal or major correction | 36, 60, 120, 220 | Establishes geometry fast, then removes coarse scratches |
| General bevel grinding before heat treat | 60, 120, 220 | Keeps the workflow fast without digging unnecessary trenches |
| Post-heat-treat bevel cleanup | 120, 220, 400 | Refines an established bevel while limiting heat buildup |
| Fine satin-ready finish | 120, 220, 400, 600 | Produces a more uniform surface for hand finishing or a clean machine satin |
The biggest jump in that sequence is usually from 60 to 120 grit, and it works when the 120 belt is sharp, run correctly, and given enough time to erase every 60-grit line. If you are seeing stubborn deep scratches at 220, the issue is often not that you need an 80-grit step. It is that the 120-grit pass was rushed.
A coarse belt is for geometry, not finishing
Use 36- and 60-grit belts to establish the bevel, correct the cutting edge centerline, remove scale, and bring the blade close to its target thickness. Ceramic belts earn their place here because they cut aggressively and stay effective under pressure. They are also capable of making deep scratches quickly, especially on thin blade stock.
Do not carry a 36-grit belt farther than necessary. Once the bevel angle, plunge placement, and edge thickness are under control, move on. Trying to make a 36-grit surface look refined is wasted shop time. Its job is to move steel, not leave a finish.
For a stock-removal knife, many makers establish the primary bevel at 60 grit and leave the edge thick enough to survive heat treat. After heat treat, they return at 120 grit to clean scale, true the bevels, and begin the finish progression. That approach protects the geometry work while avoiding needless grinding on hardened steel.
The middle grits do the real finish work
The 120- and 220-grit steps are where clean bevels are made. These belts remove the coarse scratches while exposing uneven pressure, wavy grind lines, and incomplete plunge work that the rough belt can hide.
At 120 grit, work until the entire bevel shows a consistent scratch pattern in one direction. Check it under strong shop lighting. If you can still find isolated scratches running at a different angle, they came from the previous belt and need to come out now. Moving to 220 before that happens only makes the problem harder to see and slower to fix.
At 220 grit, reduce pressure and focus on repeatability. A rigid platen, stable tooling arm, and solid tool rest matter more as the finish gets finer. Any flex in the setup can wash out a crisp line or create a low spot that becomes obvious after finishing. A well-built 2x72 grinder with rock-solid tracking lets you spend your attention on blade control instead of correcting a wandering belt.
Match the Belt Progression to the Finish
A knife headed for a working finish does not need the same belt sequence as a kitchen knife receiving a hand-rubbed satin. Stop at the point that serves the knife and your production workflow.
For a belt-finished working knife, 220 grit is often enough. It leaves a purposeful, even surface and does not consume extra time on a finish likely to see hard use. A 400-grit finish is a strong choice when you want a cleaner satin appearance, particularly on stainless kitchen knives, hunters, and folders with more refined fit and finish.
Going to 600 grit on the grinder makes sense when the next step needs a finer foundation. That may include hand sanding, a very fine satin, or a finish where remaining machine scratches will be highly visible. It does not automatically make the knife better. Fine belts cost more, cut more slowly, and can generate heat if you dwell in one area trying to chase perfection.
Belt type matters as much as the printed grit. A sharp ceramic 120-grit belt may cut more aggressively than a worn 80-grit belt. Structured abrasive belts can leave a different pattern than conventional aluminum oxide. Cork, surface-conditioning, and fine finishing belts also have a place, but they are finishing tools, not substitutes for removing deep scratches with a proper abrasive progression.
Control Speed, Heat, and Pressure Between Grits
A VFD gives you a real advantage during bevel finishing. Run the coarse belt fast enough to remove stock efficiently, with enough belt speed to keep the abrasive cutting rather than rubbing. As you move through 220, 400, and beyond, slow the belt down enough to improve control and reduce heat. There is no single surface-feet-per-minute setting for every steel and belt, but slowing down for finish work usually prevents expensive mistakes.
Heat is especially critical after heat treat. A thin edge can discolor and lose temper faster than many makers expect. Keep the blade moving, quench frequently when appropriate, and do not lean on a dull fine-grit belt. A fresh belt removes scratches with less pressure, which means less friction and more control.
Use a flat platen when you need straight, even bevels and clean transitions. A platen assembly with a firm, replaceable face keeps the belt from developing a hollow that prints into the blade. For curved blades or convex work, a contact wheel can produce a controlled sweep, but it also changes the geometry. Do not switch from platen grinding to a wheel halfway through a finish unless that change is part of the design.
Avoid the Common Grit Progression Mistakes
The most common mistake is skipping a grit because the blade appears clean from a distance. Inspect the bevel under direct light after every belt change. Rotate the blade and look for stray scratch lines, especially near the plunge, along the ricasso, and close to the edge. Those areas are easy to miss and difficult to repair later.
Another mistake is changing directions inconsistently. If your 60-grit scratches run lengthwise, make your 120-grit scratches run at a clear angle to them. The change in direction makes leftover coarse scratches obvious. On a long blade, use deliberate passes that overlap evenly instead of random short strokes that create a patchy finish.
Finally, do not let a worn belt dictate the progression. A dull 120-grit belt can burnish rather than cut, leaving you with a shiny surface that still contains 60-grit damage. Replace belts based on performance, not just appearance. When removal slows, pressure rises, or heat becomes harder to manage, the belt has stopped saving time.
A good grit progression is a repeatable system, not a fixed recipe. Start coarse enough to establish geometry, make each step fully erase the previous scratch pattern, and stop at the finish the knife actually needs. With stable tracking, a rigid platen or wheel setup, and speed control from a VFD, your bevels will get cleaner without turning every blade into an all-day sanding project.
