Here are a couple of mallets.
The top one, I didn't really make it, I restored and transformed it. I found that really strange big rosewood mallet at a flea market. It was a really strange design and I never understood what was the initial purpose of that mallet.
It is quite heavy, it has on one side a lightly curved face, and on the other side a semi spheric face. And the strange thing was that the handle was not set in the middle of the body, but was asymmetrically set on the flater side of the body (you can see the previous location of the handle on the picture).
The tool was not balanced at all, so I cut the handle and put it in the middle, because I wanted to use is at a regular mallet. (It's a sacrilege to modify an old tool like that, I know, but ...)
If someone has an idea of the initial purpose of this tool, I would be happy to learn !
The mallet on the bottom, I made it, it is lighter, made out of beech for the head and ash for the handle. The faces are covered with leather.
