Konosuke HD 150mm Wa-Honesuki boning knife is light, hard and is one of our favorite boning knives on the site. Comes with a stabilized octagonal handle and buffalo horn ferrule. The Konosuke HD line uses a special tool steel that is semi stainless and holds a great edge. It bridges the gap between stainless ease of care and white steel's ability to take and keep a great edge. I really like these knives and the fit and finish are impeccable as usual with all Konosuke knives.
