탄소강 Carbon Steel

Carbon steel is reactive — it will rust quickly if not properly cared for. Always wash immediately after use, dry thoroughly, and apply a thin coat of food-safe oil (camellia, mineral) before storage. Over time it develops a patina that offers some natural protection and, for many users, becomes part of the knife's character. Rewarding to use, but not recommended if you want a "wash and forget" knife. 타케후 특수강, 일본

V-Toku 2(V특2호, V-Special 2)는 타케후 특수강이 클래식한 히타치 청2강을 재해석한 강재입니다. 합금 탄소강으로서 화학 조성이 청2강과 매우 유사하며 바나듐이 소량 첨가되었습니다. 타케후의 높은 순도 관리와 결합되어 청2강보다 내마모성이 다소 향상되었습니다.

V-Toku 2는 우수한 경화능을 갖추고 있어 HRC 64까지 담금질할 수 있으며, 많은 제작자들이 이러한 고경도를 활용해 식재료를 매끄럽게 절단할 수 있는 극도로 얇은 칼날을 제작합니다. 또한 타케후는 구리 또는 브론즈 층이 포함된 적층 빌렛도 생산하므로 유럽 및 미국 제작자의 나이프에서도 V-Toku를 찾아볼 수 있으며, 이를 통해 많은 셰프들이 탄소강 나이프의 뛰어난 절단감을 경험할 수 있습니다.

What's in V-Toku 2

What each element does in your knife.

V-Toku 2 element composition
Element	Composition	What it does in your knife
WTungsten	1.0–1.5%	Forms hard carbides for wear resistance and edge stability, and keeps the steel hard even at elevated temperatures.
CCarbon	1.0–1.1%	The primary hardening element. More carbon means a harder edge that holds longer — but past a point it trades away toughness and rust resistance.
CrChromium	0.2–0.5%	Raises corrosion resistance; at roughly 13%+ free chromium the steel qualifies as stainless. Also improves hardenability and wear.
MnManganese	0.5%	Aids hardenability and strength and acts as a deoxidiser in smelting. Too much can reduce toughness.
SiSilicon	≤ 0.35%	Strengthens the steel matrix and acts as a deoxidiser, improving hardness and resistance to oxidation.
NiNickel	≤ 0.25%	Improves toughness and ductility without sacrificing hardness, and adds a small boost to corrosion resistance.
VVanadium	≤ 0.2%	Forms extremely hard vanadium carbides for superior edge retention, and refines the grain for a finer, tougher edge.
PPhosphorus	≤ 0.03%	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.
