I purchased this on this site for 45,000 yen. There is a 1cm line near the tip, about 10cm from the end, and a scratch on the back. Please check the photos. (Photos 6 and 12) I believe there are no problems with its use. Please understand that this is a used item. Total length: Approximately 45cm Blade length: Approximately 30.5cm (from the tip to the machi) Blade width: Approximately 3.6cm Blade thickness: Approximately 4mm Weight: Approximately 253.1g It's a very nice knife with a beautiful pattern.
