Grinding and Sharpening VG-10: Belt Recommendations & Technique
VG-10 grinds and sharpens in the moderate, easy-to-manage range for premium stainless steels. Standard ceramic or zirconia belts and ordinary sharpening stones work well, no need for diamond or CBN abrasives.
VG-10 grinds in the moderate, well-established range for premium stainless steels, easier than high-carbide CPM steels like CPM 20CV or S30V, but slightly more demanding than a lean steel like AEB-L. It has decades of production history behind it in Japanese kitchen cutlery, so the belt and sharpening approach is well understood.
Belt Selection
Standard ceramic or good-quality zirconia belts handle VG-10 well. It does not demand the premium structured abrasives that harder, more carbide-heavy steels benefit from.
Grit Progression
| Stage | Grit |
| Profiling / heavy stock removal | 50 |
| Bevel refinement | 80 |
| Pre-finish | 120 |
| Finish grinding | 220 |
Technique
Standard technique applies well: moderate belt speed, light controlled passes, and a coolant mister to protect the temper. Given VG-10’s frequent use on thin kitchen-knife grinds, take extra care to avoid overheating thin edges, similar to the concerns with thin AEB-L stock.
Sharpening
VG-10 sharpens well with standard sharpening stones and does not require diamond or CBN abrasives. Its fine, cobalt-hardened grain takes a very keen, precise edge, which is exactly why it remains a top choice for Japanese-style kitchen knives.
Common Mistakes
- Buying premium high-cost belts unnecessarily; standard belts handle VG-10 well.
- Overheating thin kitchen-knife edges during finish grinding, drawing the temper near the bevel.
- Grinding at low speed with heavy pressure, which loads belts faster instead of cutting cleanly.
Safety
Wear a full face shield and appropriate respirator. Keep coolant and misting systems clear of electrical components. Inspect belts for fraying or thinning before mounting.
