I have used the saw. When I completed it I went outside and pruned a few trees. It works as well as a 12" saw will. I'm not completely satisfied with the hardware store blade, but the setup is small, light and works. My ax is a cheaply from a big box store. I liked the casting and spend quite a bit of time refining it. I reworked the handle, a bit, too. It's sharp enough to shave with, now.
My leather and findings come from Landwerland Leather Company here in Indianapolis. They've been in business since 1909 and haven't changed a thing. I'm not sure how they handle phone orders but you could give them a try, 317 636 8300.
