Tetsujin Ginsan Ukiba K-tip Gyuto 240mm Ebony Handle

Not quite - and it is the single most common point of confusion when people shop for a kiritsuke. The two knives share the same striking angled, reverse-tanto tip, but underneath that tip they are very different tools.

A K-tip gyuto is normally a double-bevel knife: it is ground on both sides like any Western-style chef's knife, so it is forgiving to use, and sharpened exactly the way you would sharpen a normal gyuto. You get the dramatic kiritsuke look with the everyday usability of an all-purpose chef's knife.

A traditional kiritsuke, including the kiritsuke-yanagiba (slicer), is a single-bevel knife, ground on one side only. It is historically a master chef's knife: it takes real practice to use well, is set up for right-handed users by default, and needs single-bevel sharpening technique to maintain.

So if you want the kiritsuke silhouette with no learning curve, choose a K-tip gyuto. If you specifically want the traditional single-bevel discipline - and the precision it allows on fish and vegetables - choose a true kiritsuke. At Knives and Stones we stock both, and each product page tells you which construction you are looking at.

Ginsan steel, also known as Silver #3 or G3, is a stainless steel made by Proterial in Japan, containing 0.95 to 1.10% carbon and 13.00 to 14.50% chromium, and it is used in Japanese knives because it combines the sharpness and ease of sharpening of carbon steel with the rust resistance of stainless steel. It is a fine-grained steel that takes a very sharp edge, and rated by Proterial at over 59 HRC, it offers a practical balance of edge retention and sharpenability for everyday kitchen use.

The name "Ginsan" (銀三) literally means "silver three," referring to its Silver #3 designation. Its moderate chromium content makes it far less reactive than carbon steels, so it won't discolor or rust as quickly, while its carbon content keeps the edge keen and responsive on the stones. For home cooks and professionals who want a stainless knife that still feels like a traditional Japanese blade, Ginsan is a common middle ground.

Yes. Proterial lists the steel as GIN 3 (銀紙3号) with 13.00 to 14.50% chromium, above the Japan Stainless Steel Association's 10.5% minimum for stainless steel.

Proterial describes it as a stainless steel with hardness and sharpness comparable to carbon steel, used in various kitchen knives and scissors, and the association notes that stainless, strictly, means it rusts less. Wash the knife and dry it after use.

Tetsujin Ginsan Ukiba combines Toru Tamura's forging with Naohito Myojin's sharpening. It has a stainless-clad sanmai blade and an Ukiba finish. K&S recommends the line for first-time buyers, students and professional cooks.

A hamaguri-ba edge, written 蛤刃, is a convex edge shape, and it is the shape the workshop 明神利器製作所 sharpens its knives to. Kochi City's craft page records that Myojin Riki learned it over several years of training in Fukui.

The same page says the workshop also takes sharpening-only orders from outside Kochi.

Yes. Kochi City's craft page for his workshop 明神利器製作所 says the work runs from forging through finishing in one continuous process, 鍛造から仕上げまで一貫して行う.

That page lists the workshop in Susaki, Kochi.
