Hiroshi Kajihara, owner and blacksmith of Kurotori Hamono, produces some of the most refined Ginsan blades coming out of Kochi today. We are proud to introduce this exclusive mirror polished line, crafted with precision and a clear dedication to traditional hammer forged techniques. Chefknivestogo is honored to serve as the premier international dealer for these exceptional knives.
Each knife is constructed in san mai using a Ginsan stainless steel core hardened to approximately 61 HRC. Ginsan, also known as Silver 3, is prized for its fine grain structure, excellent edge retention, and ease of sharpening while remaining fully stainless. The grind is an even 50/50 double bevel, offering balanced performance for a wide range of users. A flawless mirror polish highlights the clean lines of the blade and reflects Kajihara san’s meticulous craftsmanship. The upgraded octagonal handle is made from 4,000 year old bog oak, adding striking visual character along with excellent balance and a comfortable, secure grip.
Care Instructions: This knife features stainless cladding and a stainless Ginsan core for easy maintenance. Hand wash and dry promptly after use. Avoid cutting frozen foods or hard materials and do not twist the blade during use.

I’ve been using this knife for a few months now, and it was incredibly sharp right out of the box. As a sous chef who does a lot of prep, I’m impressed with how well it holds an edge—about four weeks of heavy use with only an occasional touch-up on a ceramic rod. It’s lightweight, thin, and well-finished, with great balance and smooth performance. Overall, an outstanding knife that delivers every day in a busy kitchen.
