The Hatsukokoro x Shimizu Ginsan Single Bevel line is a small batch of single-bevel knives forged from Ginsan steel and sharpened by Masaya Shimizu, featuring a pronounced spine curvature (Sori) designed for deep cuts into large proteins, and it is best suited for professional chefs and enthusiasts with a higher budget.
This collection is currently represented in stock by the Hatsukokoro x Shimizu Ginsan Damascus K-tip Oozori Yanagiba 330mm, priced at $700. The defining physical trait of this line is the Sori in the spine, which mimics the profile of a Katana; this geometry offers a functional advantage over standard straight profiles when slicing through larger chunks of protein. While the catalog notes the line is easy to look after and offers excellent fit and finish, the primary trade-off is the high budget required, making it a specific investment for those who need the performance of a deep-curve single bevel.
