This is a Sakamitsu brand kiridashi knife. There are some rust and scratches in several places, but the blade is generally in good condition. Please check the images carefully. The cutting edge and the back are not perfectly flat, so please sharpen them before use. Total length: approx. 183mm Blade width: approx. 18mm (width at the base of the blade) Blade length: approx. 53mm Thickness: approx. 2.5mm The steel type is unknown. The item for sale is only the kiridashi knife itself, and the whetstone in the image is not included. I have forgotten which box it came in when I purchased it, so I will include a box I have on hand. Thank you for looking.
