There are a couple good axe-refurbing pages on facebook. I got booted from one for posting s dis-allowed type of axe... but there's a lot of info there.
I posted an add on craigslist looking for old broken axes/ hand tools and got a ton of responses. Bought 50-ish heads from a guy for $100. 7 double-bit, 7 regular, 7 malls, a bunch of sledge hammer heads, hatchet heads, pick axe, axe/adze, hand made blacksmith tools, root axe and about 10 handles, some of them never hung (mounted).
Another guy sold me an old hand drill and a bunch of large bits (for cabin or ship building..) for $40. Then threw in 4 axes for $10! :-O
Got a couple from the WPA "new" deal after WWI.. a few hand made blacksmith hammers/ tools. some "Kelly" which are pretty sought after.
Might try advertising locally for old hand tools... most of them are just rotting away in sheds:-/
So I've got some restoring to do!! Going to plant a a bunch of mountain ash (Rowan) this year, the berry is medicinal, great wildlife and stock feed, sapplings and shoots are good strait arrow wood, and larger branches and trunks make good tool handles.
