Stainless Stainless Steel

"Stainless" means stain-resistant, not stain-proof. In kitchen use, the steel can still discolour or pit if exposed to acidic environments — citrus, vinegar, or salt water — for extended periods. Wash and wipe dry after every use, and avoid leaving the blade soaking in water. With basic care, a stainless knife is very low-maintenance and a great everyday choice. 타케후 특수강, 일본

What's in VG XEOS

What each element does in your knife.

VG XEOS element composition
Element	Composition	What it does in your knife
CrChromium	18.0–19.0%	Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear.
MoMolybdenum	1.85–2.0%	Improves hardenability and toughness, boosts corrosion resistance, and helps the steel hold hardness under heat.
CCarbon	0.7–0.8%	The primary hardening element. More carbon means a harder edge that holds longer — but past a point it trades away toughness and rust resistance.
MnManganese	0.68%	Aids hardenability and strength and acts as a deoxidiser in smelting. Too much can reduce toughness.
VVanadium	0.35–0.45%	Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge.
SiSilicon	0.25–0.3%	Strengthens the steel matrix and acts as a deoxidiser, improving hardness and resistance to oxidation.
NiNickel	0.12%	Improves toughness and ductility without sacrificing hardness, and adds a small boost to corrosion resistance.
WTungsten	0.11%	Forms hard carbides for wear resistance and edge stability, and keeps the steel hard even at elevated temperatures.
CuCopper	0.08%	A minor player in knife steel — a small lift to corrosion resistance, and often present only as a residual rather than a deliberate addition.
NbNiobium	0.01–0.02%	Forms some of the hardest carbides in steel — even finer than vanadium's — for wear resistance and strong grain refinement.
