Takeshi Saji SG2 Black Damascus

Sanmai - Stainless Damascus Clad Etched SG2 / R2 / Stainless Stainless Clad Takefu, Japan

Takeshi Saji SG2 Kurozome Black Damascus is another signature line produced by Takeshi Saji, featuring high performance steel, dazzling appearance and unique blade geometry that leads to a smooth cutting experience, these knives are allrounders in the league of high end knives.

As the core member of TAKEFU Knife Village, Saji Uchihamono was a big name in the industry that represents the highest level of knifemaking in the Echizen area. The factory utilises laminate billet from Takefu Special steel and combines with traditional forging skill inherent from the past, creating knives that are stunning in appearance and amazing in sharpness. From forged stainless Damascus to rainbow cladding knives, Takeshi Saji was quite pioneering at that time. This laid a solid foundation for his legacy and many of the designs stood up against the test of the time and became a classic that was praised by knife lovers and chefs alike, this includes this SG2 Kurozome Damascus line.

It is not uncommon to see the combination of stainless damascus and deep etching that create strong contrast, but still, the dense texture and on the bevel of the knife is fascinating whether when using or just looking at. Beneath this striking appearance is a solid performing blade, as the powder stainless SG2 steel is still considered as one of the best cutlery steel in the industry that offers an excellent edge retention while being fully stainless.

When looking down the coil of the knife, we can find the secret behind the smooth cut of these knives. The blade features a convex grind with a decent thickness, but the catch is, the convex continues past the Shinogi line resulting in a fusiform cross section. Which means, the thickest part of the blade is actually at the Shinogi line and it tapers towards the spine and the edge. As a result, there is more curvature when the primary bevel transitions into the Hira, thus the blade can achieve better food release without increasing the thickness of the blade.

This sharpening puts these blades easily into the top tier in terms of overall smoothness of the cut, if there is any downside, I would say it might need a thinning sooner than other types of grind like a concave grind. I would highly recommend this line for collectors and enthusiasts, or people who are looking for a high end gift. As this line also comes in Japanese handles or the more exotic and America-influenced bone/horn/ironwood handles, it can be a very unique purchase for anyone seeking a premium cooking experience.

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.
