It was stored in my grandfather's toolbox. Although there is some dirt, it doesn't seem to have been used much. I think it can still be used if you sharpen it. The blade is engraved with "Tosa Dai Tokusei" (土佐 大 特製). Total length: approximately 37cm Blade length: approximately 18.5cm I am not an expert, so I would appreciate it if you could judge the condition and details from the images. (The cover has deteriorated over time) *For shipping, the item will be wrapped in cushioning material and packed in recycled cardboard, etc.
