Kohetsu, our in-house brand of Japanese knives, is an ever-growing line of kitchen cutlery encompassing several different steel types, forging methods, and construction techniques. The most recent addition to this brand is the Shinano line. These blades are constructed from Blue #2 high-carbon steel. The inner core alloy is hardened to 62 HRC and then laminated in a softer stainless steel cladding. This adds strength and increased protection to the inner core while making maintenance much easier than with full carbon blades.
The specified hardness of 62 Rockwell for the Aogami hagane results in a durable blade that is still resilient and easy to sharpen. The blade path is set high on the face and is given a great-looking matte finish, which adds contrast to the exposed inner core edge. It has a particularly well-executed symmetrical 50/50 grind. We have paired this knife with a lovely octagonal handle made from walnut and pakka wood (please note that the handle in the photos is current, but the handle in the video is the previous version and no longer available).
This is a classic tall petty in terms of length and blade height ratios, so it is the perfect choice for in-hand cutting and getting into tight spaces and around obstacles. It also works well as a garnish prep knife or herb chopper. The short blade adds rigidity and stiffness, resulting in a quick, easy-to-control implement.Weight: 2.9 oz (82 g)

Kohetsu Shinano 120mm PettyPosted By: HPHH

Very nice petty for the $75 sale price. It is about the same shape and weight as the Tsuchi Ido tall petty/ko-deba I wanted to replace. My Tsuchi Ido is from a very obscure maker, who is likely now dead, and has been rehandled twice. My grandparents used it to prop open the sink stopper for almost a decade before I discovered it.
I sharpened it up and got rid of all the rust and straightened it out the best I could. I found I really liked its profile and cutting feel. It was also a sanmai aogai knife, likely blue
