Shoehorn. Of course, I should have thought of that. Anybody got more uses for this handy tool?
Re making it: If I remember, I got the Ti from Thruhiker. That, a lot of pipe clamps, a piece of 1/2" PVC pipe, tin snips, and a file. Oh, and the blood sweat and tears. I use a Harbor Freight punch to put holes in most all my Ti.
Difficulty, on a scale of 1-5 = 3.5. I've got a pattern, if anybody wants to make one.
