Thank you for viewing. This is a 180mm petty knife from Tojiro. I purchased it 7 years ago at the Tojiro factory shop. I rarely use petty knives, so while there are some minor scratches, I think it's in good condition. It comes with a free sharpening service ticket. (I have never sharpened it myself) It seems there is no expiration date. The customer is responsible for the shipping cost to send it to Tojiro, but everything else seems to be free. (Refinishing and repairs are separate) Please see the brand website for more details. https://tojiro.net/shop/products/detail/277?srsltid=AfmBOopWRrKu9yNJ8t8_35GA5jG-xPeOkyhcfowtzPX0A9SgfFIK2Xyi - Brand: Tojiro - Model Name: F-798 - Size: Blade length 180mm - Country of Manufacture: Japan Please let me know if you have any other questions ☺︎
