The Hatsukokoro Ryuhyo collection takes its name from the drifting sea ice of northern Japan. Each knife features high-grade SG2 stainless steel, elegant Damascus cladding, and a beautifully grained olivewood handle.
This new santoku combines top-tier SG2 powdered steel, a refined stainless Damascus finish, and lightweight construction for an exceptionally nimble feel. It’s sharp, responsive, and easy to maneuver—ideal for daily prep and equally capable with vegetables, proteins, herbs, and general kitchen tasks.
The SG2 core delivers outstanding edge retention and stainless convenience, while the polished Damascus cladding adds durability and visual appeal. At only 130 grams, the knife feels lively in hand with excellent balance and cutting feedback.
Handcrafted in Sakai, the Ryuhyo Santoku offers clean fit and finish, reliable performance, and low-maintenance care—a refined addition to any kitchen.
Care Instructions: Wipe dry after each use, avoid soaking or dishwashers, and use a quality cutting board. A quick touch-up on a 1000–2000 grit stone keeps the edge performing at its best.
