Japanese Custom Knives by Takeshi Saji: Unique Blades for Sale

Charming knife used by the Japanese farmer.

It has a razor wire, as befits a tool created to cut and not just to be displayed in display cases.

SHIN in Japanese means ‘trust’.

The SHIN is one of the largest folders in the Rockstead catalog and showcases all the typical and characteristic elements of the brand: aluminum handle with a pearl-radiant design, hardened anodization at 400 Vickers, and an insert of high-quality stingray leather (Samekawa).

This is a durable knife with strong cutting capabilities that maintains its edge for a long time. Even when used for rigorous cuts, the blade glides securely thanks to its particular sharpening.

The blade indeed has a HONZUKURI sharpening, convex on both sides, following the tradition of Japanese swords; this makes it both very sharp and sturdy, allowing it to cleanly cut a sheet of paper even after 1000 cuts through a very abrasive and resistant hemp rope.

A faithful companion for life, in which to place the utmost trust.

This knife blade is convex on both sides in the tradition of the highly praised Japanese sword. This shape is both sharp and strong, and can still slice cleanly through a sheet of paper even after the punishment of chopping and cutting through dried bamboo. Using this special blade shape is an excellent way of allowing an edge to be thick without sacrificing any of its sharpness. This knife is of preeminent sharpness. This is a durable knife with strong cutting capabilities that will last for a long time. Even when used for rigorous cutting, the blade will not bite or catch thanks to its convex shape. Other knives will often bite or catch, and may acquire nicks if pulled out suddenly.
