Blade length: approximately 139mm Blade thickness: approximately 4mm Single-edged This is a user-friendly funayuki knife. I used it to fillet horse mackerel. It has a very sharp edge and is easy to handle due to its moderate blade length, so I highly recommend it. Also, the shape is very cool. It has been sharpened, so you can use it immediately upon arrival. #Deba #AjiKiri (Horse Mackerel Knife) #Sakai
