This is a hammer that my grandfather, who was a carpenter, used. It's a hammer from the Showa era... It has been stored for a long time, so there is some rust. It looks well-used, and the smaller one has a chipped edge. It feels quite heavy... more so than it looks. Both hammers have engravings, but they are difficult to see and the details are unknown. There are three-digit numbers, but they are not clearly readable. I believe these are rare hammers, so I am offering them for sale... Thank you.
