I've been meaning to try putting a wood handle on one of my cheap harbor freight screwdrivers. I got one free my last time there, so decided to have a go at it. The ferrule is a piece of 1" copper pipe. The wood is some mesquite that I didn't know that I had in my stack of scrap. I learned a few things, and my next one should turn out better, but I'm happy with the first attempt. (Note: definitely not an original idea, several examples on IAP, I got the idea from a YouTube video - there are several)
