The spine tapers from 2.6mm at the heel to 0.8mm near the tip, while the photographed choil reveals a thin, performance-focused grind behind the edge. At only 160g without a handle, the blade gives you flexibility to tune the finished balance with the wa handle of your choice.\u003c\/p\u003e\n\u003cp\u003eIsamitsu Hamono works in Ibaraki with a lineage connected to training under Teruyasu Fujiwara. The workshop is especially sought after for high-performance carbon-steel heat treatment, keen edge formation, and handcrafted geometry. Every blade is individually forged, so subtle variations in hammer marks, kurouchi tone, profile, and measurements are part of its character.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose This Isamitsu Gyuto?\u003c\/h2\u003e\n\u003cp\u003eThis is a compelling choice for an enthusiast or professional who wants long edge life, excellent sharpening response, and a tall, versatile 240mm profile. Stainless cladding protects most of the blade face, while the exposed Aogami Super edge develops a natural patina with use. The blade-only format is ideal for a custom build, allowing you to select the handle material, length, and weight that best suit your grip and balance preference.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does blade only mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No handle is installed.
