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! It's made of stainless steel, so it's resistant to rust and highly 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!
