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. 일본 아이치

What's in AUS-8

What each element does in your knife.

AUS-8 element composition
Element	Composition	What it does in your knife
CrChromium	13.0–14.5%	Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear.
SiSilicon	1.0%	Strengthens the steel matrix and acts as a deoxidiser, improving hardness and resistance to oxidation.
CCarbon	0.7–0.75%	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	0.5%	Aids hardenability and strength and acts as a deoxidiser in smelting. Too much can reduce toughness.
NiNickel	0.49%	Improves toughness and ductility without sacrificing hardness, and adds a small boost to corrosion resistance.
MoMolybdenum	0.1–0.3%	Improves hardenability and toughness, boosts corrosion resistance, and helps the steel hold hardness under heat.
VVanadium	0.1–0.26%	Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge.
PPhosphorus	≤ 0.04%	An impurity from smelting. Even small amounts promote brittleness, so steelmakers keep it as low as possible.
SSulfur	≤ 0.03%	An impurity that reduces toughness and promotes brittleness; only ever added deliberately in free-machining steels.
