This item was received from an acquaintance. I don't know the details, but I've listed what I do know. The material is likely Yasugi Hagane Shirogami No. 2 steel. Due to long-term storage, there is rust on the blade (see photos 3, 7, 9, 11, and 12). There are cracks (see photos 8 and 9). The blade is slightly bent (see photo 11). There is a large dent (see photo 9). *Please understand that returns and exchanges are not accepted before purchasing. ■Product Name: Deba Knife ■Blade Length: 150mm ■Blade Type: Single-edged (right-handed) ■Handle: Hou (Magnolia) Round Handle ■Weight: Approximately 238g ■Spine Thickness: Approximately 8mm ■Accessories: Comes with a box *Important Notes ・After using the knife, remove any dirt and thoroughly wipe off any moisture.
