This is a very old chisel. The base metal has a unique striped pattern, which appears to be due to the use of Japanese iron. As can be seen from the construction of the tang and the back, it is a very old and rare item. There appears to be a marking, but it is unidentifiable. I am selling it to organize my collection. ★ The item for sale is only what is shown in the images. ・ As it is an old item, 　there are stains, scratches, and damage. 　Please refrain from bidding if you are sensitive to these issues. ・ Please examine the images to assess the condition of the appearance. ・ I am an amateur, so I do not know the details. 　Please confirm everything carefully before bidding. ・ The actual color may differ from the images due to the shooting environment. ★ After the transaction, 　I do not offer any support. 　After the transaction, 　returns are not accepted for any reason, 　and I cannot accept any claims.
