Thank you for viewing. This is a genuine forged O-Deba knife by Mizuno Tanrenjo, Minamotono Akitada. Recommended for professionals and serious users (commercial use). Minamotono Akitada's O-Deba knives are not widely available, and knives of this size can cost over 100,000 yen each. When purchased, it had a chipped blade, scratches, and rust, so it has been reshaped, polished, and hand-sharpened. The handle has also been replaced with a new one. We hope that this knife will contribute to the safety, health, and enjoyment of food for yourself, your family, and your customers. ◆ Product Description ・ Manufacturer or Seller: Mizuno Tanrenjo / Minamotono Akitada (MIZUNO TANRENJO/MINAMOTONO AKITADA) ・ Type: O-Deba knife / Japanese knife / Single-edged / Knife ・ Material: Steel / Wooden handle ※ The wooden handle is a commercially available item from a home improvement store. ・ Hand orientation: Right-handed / Single-edged ・ Size: Length 39.7 x Width 6.5 x Height 2.7 cm ・ Weight: 546g ・ Condition: Refurbished (used/junk) 　　　　Polished up to 15000 grit whetstone. 　　　　There are fine scratches and pitting (black spots) on the blade, but there are no problems with use. 　　　　※ Please consider the scratches and rust as unique characteristics of this knife and enjoy using it. ・ Uses: Primarily a knife for dismantling fish, but can also be used for meat and vegetables. 　　　　Can be used for home use or commercial use (professional/serious users). 　　　　Can also be used outdoors for camping, fishing, etc. 　　　　Previously, people who purchased knives of this size used them for dismantling frozen tuna. ・ Remarks: Rare item. ・ Accessories: No original box or instruction manual. ◆ Notes ・ Please check the condition in the photos. ・ Because it is a steel knife, daily maintenance is required.
