This is a Sakai Nankai sujihiki knife! The blade has been sharpened, so it's ready to use immediately! When I previously listed a sharpened knife, the buyer said it cut very well! Made of stainless steel, it's also rust-resistant and recommended! I hope you'll use it at home or at work! Brand - Sakai Nankai Blade Length - Approximately 24cm Blade Material - Stainless Steel Handle - Resin Blade Condition - Sharpened Thank you for viewing! Thank you!
