Thank you all for your input. I will post a picture when I get them done. I bought some kydex to make knife covers for my son's knives, so I will run that by her too. I'm going to make a couple and put them in my convection oven on the dehydrate cycle and see what happens. I had mentioned briefly about using the chisel covered in plastic to form the cover and that went over like lead a balloon, it's what started the whole conversation about moisture still in the leather and dryness. I feel they were very dry, she decided to let them dry for a couple weeks before using. She did say they fit better than the ones I made dry.
I cut a 3 inch piece of bamboo in half and folded a 6x2 5oz veg tanned strip over it long way after wetting, then I stitched. It looks good, I didn't bevel the edges or anything because well, it's tool cover. She's going to write the chisel size on the outside. Did burnish the edge a bit with gum, just because I like it that way. I will see. Thanks again.
