Kurosaki Senko SG2

Sanmai - Stainless Clad Tsuchime SG2 / R2 / Stainless Stainless Clad Takefu, Japan

Yu Kurosaki's Senko line is built on SG2 powdered stainless steel, which holds a long edge and stays sharp under heavy use. The hammered pattern is inspired by flashes of light, and its texture helps food release from the blade, for a smoother, more efficient cut. The Senko knives are well balanced and ergonomic, precise and comfortable whether slicing delicate vegetables or tougher proteins, for professional chefs and home cooks alike.

Frequently asked questions

SG2 steel knives at Knives and Stones

SG2 (Super Gold 2, which Takefu writes as SPG2) is Takefu Special Steel's own blade steel, made by powder metallurgy. Takefu says it meets all four of what it calls the major requirements for a blade: high hardness, high toughness, good wear resistance and excellent corrosion resistance.

SG2 runs 61 to 65 HRC depending on the maker, and Takefu does not publish its composition. As of 18 October 2026, 291 of the knives we list have SG2 in their title.

What is the difference between VG10 and SG2?

Both are Takefu blade steels, and they differ in class and in what Takefu publishes about each. Takefu lists VG10 as a stainless steel with 1.00% carbon, 15.00% chromium, 1.00% molybdenum, 0.25% vanadium and 1.55% cobalt, at a hardening hardness of HRC 60 or more.

Takefu describes SG2, its Super Gold 2, as a blade steel created by powder metallurgy, lists its composition as not disclosed, and SG2 runs 61 to 65 HRC depending on the maker. Takefu also calls SG2 a powdered stainless high-speed steel.
