This tall petty arrived from the manufacturer with a dent in the handle, as shown in the 4th picture.
Yamashin works out of Tosa, Japan — one of the country's most prolific knife-making regions — and has spent generations building a reputation for blades that earn their place in a working kitchen. No frills, no shortcuts, just honest construction and real cutting performance. Shirogami — meaning white paper steel — is among the purest carbon steels available, prized by sharpening enthusiasts for how easily it takes a razor edge and how well it holds it through heavy use.
This petty is hammer-forged in a san mai construction, with a Shirogami #1 core clad in soft iron that develops a beautiful patina over time. At 120mm, it is a natural fit for in-hand work — peeling, trimming, and detail cuts where a longer blade would feel unwieldy. The extra blade height of 40mm sets it apart from most petties in this size range, adding useful knuckle clearance and making it easy to scoop small cuts from the board. The walnut octagonal handle with black pakka wood ferrule completes a knife that looks and feels far more expensive than it is.
Carbon steel care is straightforward. Wipe the blade clean during use and dry it immediately after washing. Avoid leaving water or acidic foods on the blade for any length of time. The soft iron cladding will develop a natural patina with use, which adds character and provides a measure of protection. Each knife is made by hand so measurements may vary.Maker: Yamashin
