Iron Clad Arare SG2 Tsuchime

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

Arare (霰, Small Hail) is a fitting name — looking at the blade, the surface of the Hira is covered in a dense field of small, geometric square and diamond-shaped indentations with defined, sharp edges arranged in a tight repeating pattern. The texture meets the Shinogi line where it gradually fades as the bevel thins out during grinding and polishing, leaving the Migaki finished bevel below in clean contrast with the textured Hira above. It's a more considered and refined take on Tsuchime than the organic, irregular hammer marks you'd typically find, and if the pattern looks familiar, it's not a coincidence — a very similar texture appeared on a special edition of the Minamo SG2 line, which hints at a shared manufacturing origin, likely somewhere within the Takefu Knife Village network that Shibata has strong connections to.

The line is curated by Shibata, and the execution reflects his priorities clearly. The spine sits at a slim 2mm, paired with a concave grind that brings the bevel down to a low thickness behind the edge. Food release is handled by the Shinogi line — as the slice reaches that geometrical transition the food peels away cleanly, and the concave geometry keeps the thickness low enough that the knife doesn't wedge badly even in denser produce. It's a well-balanced geometry that performs beyond its price bracket and competes for the best value knife we sell.

The core steel is SG2 (also known as R2), one of the most capable powder stainless steels in the industry — excellent edge retention, full stainlessness, and a hardness that supports the thin geometry well. This is genuinely exceptional value for an SG2 knife with this level of finish and sharpening behind it, sitting at a lower price than the Ryuhyo line while offering an arguably more characterful surface and comparable cutting performance.

Frequently asked questions

What does Arare mean on the Arare SG2?

Our line page calls the pattern Arare (霰), small hail. Our line page describes the blade face above the shinogi carrying a dense field of small square and diamond-shaped indentations that fade toward the shinogi line, with a polished bevel below.

We list the Arare SG2 by Iron Clad as a nakiri, gyuto, bunka and santoku.

What steel is the Arare SG2, and will it rust?

Our line page lists an SG2 core in a stainless clad blade. Takefu lists SG2 as its own powder-metallurgy blade steel and calls it a powder stainless high-speed steel.

The JSSA says stainless strictly means a steel that rusts less, not one that never rusts, so we suggest drying the knife after washing.

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.
