Well the hammer looks like a 19th Century hammer. The condition would be surprisingly good for something even thousands of year old (wood usually rots except in unusual conditions) and the supposed carbon date is consistent with a 19th century origin. So really it's worth asking what evidence is there that it is anything older ?
1. I suppose there's not a lot of ways to design a hammer.
2. Thanks for the links. I don't know where the hammer was found, so far as location dating goes, but it appears that it will depend a lot on dating data and I don't know how much of that's been done.
