Sukenari SG2 Damascus Santoku 190mm w/ Snakewood Handle

The gyuto came to Japan with the beef-eating culture of the Meiji era, and that is where its name comes from. Tojiro says it is used for all kinds of cooking, which is why it is also called the chef's knife.

The santoku is a household knife that combines the good points of the nakiri and the gyuto. Tojiro describes it as all-purpose, from vegetables to meat and fish, double-bevel and built on the same construction as a Western knife.

Choose a gyuto if you want more length and reach. Choose a santoku if you want a shorter all-purpose knife. Tojiro's own size figures: gyuto 150 to 210mm for household use and up to 360mm for professional use, santoku 165 to 170mm for household use.

Match the shape to your stroke. Rock chopping keeps the tip on the board and rolls the curved belly through the food, so a gyuto or a Western chef's knife suits it, and Japanese knives rock fine as long as you rock gently.

Up-and-down chopping, the Chinese style, wants a straight run of edge, so a nakiri, usuba, santoku or bunka suits it better; a curved edge chopped straight down easily leaves pieces joined. Neither shape is better; it depends on how you cut.

A Japanese dictionary explains the name of the santoku (三徳包丁) as coming from the three things it handles: meat, fish and vegetables. The same dictionary entry points from the santoku to the bunka (文化包丁), treating the two as one knife.

One Japanese knife maker guide distinguishes the two by the tip. It says that in the Showa era the bunka was made with its tip cut at an angle, and the santoku came after it by rounding that tip.

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.

Neither is objectively better, it just depends on whether you value stainless convenience or a laser-sharp carbon edge. Go with SG2 if you want a knife that holds a screaming edge without any babysitting. Choose AS if you are chasing the thinnest possible edge and don't mind wiping the blade down after every use.

SG2 is a powdered stainless steel from Takefu, 61 to 65 HRC depending on the maker. It is tough and resists corrosion, which is why I reach for it when working with acidic foods. Aogami Super is high carbon, and Proterial gives it a hardening hardness of over 60 HRC. It takes a very keen edge, but it will rust if you neglect it.

We can't confirm that from a steelmaker. SG2 (Super Gold 2, which Takefu writes as SPG2) is Takefu Special Steel's own blade steel, made by powder metallurgy. Takefu does not publish its composition; SG2 runs 61 to 65 HRC depending on the maker.

As of 18 October 2026, we found no steelmaker page for a steel called R2. Some knives on our shelf are listed as SG2/R2: six as of 18 October 2026, from Kurosaki, Shiro Kamo and Yoshimi Kato.

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.
