Yoshimi Kato SG2 Minamo

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

The Minamo is the latest offering from master Yoshimi Kato from Kintaro Hamono of Takefu Knife Village. The Minamo line is forged with the SG2 powdered steel that is very fine, sharp and has great edge retention.

The elegant hammered "Minamo" pattern is inspired by the summer Thunderstorm, and the way they lines up along the blade forms patterns looks like ancient coins. As master Kato has been working with Master Kurosaki for a very long period of time, and their knives are highly similar in terms of design and performance: super thin behind the edge, with a great OOTB edge and excellent food penetration, on top of that, they often put very unique patterns that differentiate their knives from other lineups, just like how this Minamo line does.

Like any other knives made by Yoshimi Kato, these blades are thin and nimble in hands, while retaining that excellent trait, the line bring some shiny appearance along with good performance. Considering the level of finish, artistic value and the SG2 core steel, I believe the pricing for this line is actually very good, thus I would bring it out for anyone who is after a SG2 knife.

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.
