I have done hundreds of Steve's keychains. My daughter is a principal and every time she changes schools I do all the teachers as Christmas presents. I also have done lacrosse teams and baseball teams for my grandkids. I enjoy cutting them.
I use scrap hardwood that is about 3/8 inches. Cherry is my favorite to cut but have done maple, oak, and walnut.
