I don't know what the wood is, and I can't read the characters on the metal parts except for "300," so the details are unknown. The wood condition isn't great, and the metal parts have scratches, dirt, rust, and dents, so this is being sold as a junk item. Please carefully review the product page and images before making a purchase. I will wrap the item in bubble wrap and ship it via Yu-Packet Post in a box that fits through the post, using Yu-Yu Mercari delivery. I apologize for the inconvenience, but please read my profile before considering a purchase. I am not accepting price negotiations. Thank you for your purchase. Thank you for reading to the end. #JunkItem #Hammer #Genno (Japanese hammer) #300g #DetailsUnknown
