Yamashin Blue #2 Kurouchi Petty 150mm

Yamashin makes simple, honest knives for a wide range of home and professional users, and this 150mm petty is a good example of what that simplicity delivers: a Blue #2 carbon steel core at the price of a stainless utility knife, wrapped in reactive soft iron cladding with a kurouchi finish. Kaki-san hammer forges this in Tosa, Japan, and the result is a small knife that is more capable than the price suggests.

At 154mm blade length and 30mm tall it is a narrow, precise utility knife suited to in-hand work, slicing smaller proteins, and detail prep. The red sandalwood handle with colored pakka wood ferrule gives it a warm, traditional look.

What Customers Are Saying: Three reviewers, consistently positive. One emphasizes the excellent overall experience with CKTG and specifically praises the chip repair service alongside the knife itself. Another calls it a great buy for the money. A third purchased it to try a traditional carbon steel experience and found the quality exactly as expected.

Care Instructions: Blue #2 carbon steel is reactive, so the entire blade - both the core edge and the soft iron cladding - will develop a natural patina with use. Wipe and dry the blade immediately after use, avoid leaving acidic foods against the blade, and apply a light coat of camellia oil for longer term storage. Hand wash only.
