Kobocho knife, Shirogami 1, kurouchi finish - Yamashin
This variant is currently sold out
A great little knife for working on the board in a rocking motion, or in the hands for those who like to hold the blade.
SHAPE: Kobocho. Literally small knife, this funky little blade is shaped like a small deba but is much thinner.
STEEL: Shirogami (white paper) 1 steel. This steel has the highest amount of carbon out of the paper steels so will get crazy sharp easily. It is a very reactive steel so best kept dry although the kurouchi finish will help inhibit rust.
FINISH: Kurouchi. This is a traditional, rustic finish achieved by leaving the furnace scale from the forging process on the blade rather than polishing it off. It has the advantage of reducing the reactivity of the surface of the knife and gives the blade a stylish, matt black finish. This blade has also had a lacquer applied to it which will further inhibit rust, over time it will slowly come off. It is worth noting that during the application process some of the lacquer can be applied to the edge masking its sharpness. This can be removed using a sharpening stone or by very lightly drawing it across a fine steel, preferably a ceramic one.
HANDLE: Octagonal walnut wood handle with pakka wood ferrule suitable for both lefties and righties.
MAKER: Yamashin - Tose, Japan
BEST FOR: Everything small apart from bones.
