So nice to see someone else doing this.
Here is a hammer I found in a farmyard ditch back in the 1980s. I did basically the same, but potted the new handle in with epoxy before doing the metal wedge.
And somewhere over the years I had some of that rubbery goo to coat tool handles for non-slip, so it got that treatment.
can't imagine how old this thumper-head is. It is great for garden stakes and other things where the need is to "get a bigger hammer".
It is just lovely to fix up old things and continue to use them!
