Higonokami VG10 Steel Folding Knife - Pocket

A petty is a small utility knife, from the French petit. It is commonly shaped like a small gyuto and runs from 120 to 150 mm, up to 180 mm. Its clearest role is detailed work where a larger knife feels cumbersome: fruit peeling, garnish work, condiments, and small board work beside a gyuto or santoku.

A knife maker, Tojiro, frames the petty as a useful second knife, not an automatic necessity, and recommends santoku plus petty or gyuto plus petty combinations. It is not a replacement for a full size chef's knife; it lacks the blade length and belly for efficient chopping, rocking, or breaking down larger proteins. Treat it as a precision tool, not an all-rounder.

Petty knife lengths vary by maker: KAI's guide defines a petty (ペティナイフ) as a small knife with a narrow blade measuring 150 mm or under. Its table gives 90 to 150 mm, and it describes the shape as a smaller gyuto with a pointed tip.

We list petty knives from 70 mm to 165 mm, including lengths above the limit used in KAI's guide.

Yes, it can. Takefu, which makes VG10 (V金10), lists it among its stainless steels, and the JSSA notes that stainless strictly means rust-resistant, not rust-proof.

Takefu lists VG10's chromium content as 15% and describes its corrosion resistance as excellent. We recommend drying the knife after washing.

Takefu, the steelmaker behind VG10, gives HRC 60 or more as its hardening hardness, measured straight after quenching. The hardness of a finished knife depends on its maker.

Takefu says the steel's 15% chromium, 1% molybdenum and 1.55% cobalt give it high hardness and a long-lasting edge, and that it is easy to sharpen.

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.

Yes. The Higonokami (肥後守), a folding pocket knife, is made by Nagao Kanekoma in Miki City, Hyogo.

The company's own site dates its start to 1894 and counts five generations of makers down to Mitsuo Nagao, saying its line is the only one passed down among Higonokami makers.
