Tagayasan (or wenge)

These wood handles complement Kanso’s full-tang blades. In Japan, this unusual dark-grained wood is known as “iron sword wood” for its incredible durability. The wood’s hardness requires extra handcrafting during manufacturing but will provide its owner with a lifetime of service. The tagayasan handles are angled to enable a comfortable pinch grip while cutting.
