Before hammers it was barrel knives. I like making Barrel knives and I learned an awful lot from making them.
If you do not know anything at all about Barrel Knives I recommend starting here: http://kniver.blogspot.com/2007/10/barrel-knives-from-eskilstuna-per.html

If you still want help making a barrel knife please reach out. I am only too eager to share the little I know! Here are some pictures of my past work:
