For a VG-10 kitchen knife, a 1000-grit stone handles repair and everyday touch-ups, and a 4000 to 6000-grit stone gets you a proper kitchen-sharp finish. Anything above 8000 is chasing a mirror polish that a home cook will rarely notice on a cutting board. Two stones — one in the 1000 range, one in the 4000–6000 range — cover essentially everything VG-10 needs.
The confusion around this usually comes from grit charts built for much harder specialty steels or straight razors, where the finer end of the scale actually changes how the edge feels. VG-10 sits at a hardness (around 60–61 HRC) where a mid-range progression does almost all the useful work.
Why VG-10 doesn’t need the very top of the grit scale
VG-10’s carbide structure is fine enough that a 4000–6000 grit finish already produces a genuinely sharp, smooth-cutting edge — the kind that slices a tomato skin without pressing down. Going finer than that, into 8000 or 10000 territory, mostly changes how the edge looks and how it feels catching your fingernail, not how it performs cutting food. That level of polish matters more for straight razors and for people who enjoy the process for its own sake than for a knife that’s going back into a cutting board an hour later.
The two-stone progression that actually covers it
| Grit | Job | Skip it if… |
|---|---|---|
| 400–600 | Repairing chips, major reprofiling | Your edge isn’t damaged — most people never need this stone |
| 1000 | Setting a new edge, routine restoration | Never — this is the workhorse grit |
| 4000–6000 | Refining to a kitchen-sharp finish | Never — this is where “sharp” actually happens |
| 8000+ | Mirror polish, minor final feel | You’re not chasing a show edge — most home cooks can skip this |
What actually changes if you skip a step
Jumping straight from a 1000-grit repair stone to a knife drawer skips the refinement step entirely — the edge will cut, but it’ll feel coarser and dull faster than one finished properly. Jumping from 1000 straight to 8000, skipping the middle grit, leaves deep scratches from the coarse stone that the fine stone alone can’t remove in a reasonable amount of time; you’ll spend far longer polishing than you would have just using the middle grit first. The progression exists because each stone is undoing the scratch pattern of the one before it, not adding a separate, unrelated step.
Does the steel change the grit strategy, or just the stone?
The grit numbers that matter don’t really shift steel to steel — a German stainless knife and a VG-10 knife both benefit from roughly the same 1000-then-4000/6000 progression. What changes is how the stone itself should behave: VG-10’s higher hardness means a very soft stone will dish and glaze faster under it than it would sharpening a softer German blade, which is part of why splash-and-go ceramic stones (Shapton-type) have become popular specifically for harder Japanese steels — they hold up better against the harder edge.
Frequently asked questions
Is a 1000-grit stone enough for VG-10?
It’s enough to get the edge sharp and functional, but the finish will be coarser than most people want for a kitchen knife. Pairing it with a 4000–6000 stone gets a noticeably better result.
Do I need an 8000-grit stone for a VG-10 knife?
No, not for kitchen use. It produces a finer polish than most cooking tasks require. It’s a nice-to-have for enthusiasts, not a functional necessity.
What’s the minimum stone setup for a VG-10 knife?
One stone around 1000 grit and one around 4000–6000 grit. That combination handles repair and finishing for the vast majority of home use.
