VG-10
What it is
VG-10 (V-kin 10-gō) is a premium stainless steel from Takefu Special Steel — for decades the workhorse "super stainless" of mid-to-upper Japanese cutlery, the steel beneath countless Damascus-clad gyuto and santoku. It offers a strong balance of edge retention, stain resistance, and reasonable ease of maintenance, and is what most cooks encounter first when they step up to quality Japanese knives.
The science & materials
VG-10 carries roughly 1% carbon, ~15% chromium (well into stainless territory), plus molybdenum, vanadium, and a touch of cobalt. It hardens to about 60–61 HRC — harder and more edge-retentive than German stainless, while remaining corrosion-resistant and not too difficult to sharpen. Its vanadium forms fine carbides that refine the grain and aid edge-holding. The trade: at a high polish VG-10 can be a little chip-prone (its carbide structure is coarser than powder steels), and purists find its edge slightly less fine than carbon steel or modern powder stainless. It is usually laminated with softer stainless cladding, frequently in a decorative Damascus pattern.
How it's used
VG-10 is sharpened on standard water stones (it responds well, if not quite as easily as carbon steel) and maintained as ordinary stainless — dry it, don't dishwasher it, but no oiling or patina management. Its forgiveness makes it ideal for cooks who want high performance without carbon-steel fuss.
Regional & cultural traditions
VG-10 became something close to an industry default for premium stainless Japanese knives and is produced and finished by makers across Japan (and imitated abroad). The ubiquitous Damascus-clad VG-10 gyuto is, for many Western buyers, the face of "Japanese knife."
Cultural & historical context
As a mid-late-20th-century engineered stainless, VG-10 represents the moment Japanese cutlery successfully married traditional geometry and lamination to modern corrosion-resistant metallurgy — bringing high-performance Japanese knives to a global, low-maintenance market.

When to use
Choose VG-10 as the default "first serious Japanese knife" steel: keen and edge-retentive enough to feel a clear step up from German stainless, yet low-maintenance and widely available across price points. Over carbon steel, choose VG-10 for stain resistance and easy care; over SG2/ZDP, choose it for lower cost and easier sharpening.
What goes wrong
Pushed to a very acute, highly polished edge it can micro-chip rather than roll; treated like a German knife (bones, prying, glass boards) it chips outright. Its edge, while excellent, won't match a well-sharpened white-steel or SG2 blade at the very peak — a distinction only finicky users notice.
