Thank you for viewing. This is a Hon-tanren (genuine forging) O-Deba knife by Mizuno Tanrenjo, Minamoto Akitada. It is for professional/commercial use. Minamoto 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 blade chips, 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 happiness of you, your family, and your customers through your food. ◆ Product Description ・ Manufacturer or Seller: Mizuno Tanrenjo / Minamoto Akitada (MIZUNO TANRENJO / MINAMOTO AKITADA) ・ Type: O-Deba knife / Japanese knife / Single-edged / Knife ・ Material: Steel / Wooden handle ※ The wooden handle is a commonly 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. 　　　　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 breaking down fish, but can also be used for meat and vegetables. 　　　　Can be used for home use or commercial use (professional / for professionals). 　　　　Can also be used outdoors for camping, fishing, etc. 　　　　Those who have previously purchased a knife of this size have purchased it for breaking down tuna (frozen). ・ 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.
