I got a nice hunk of buggy spring n the end is already curled n could accept a handle. I'd like to make a froe out of it. Does a froe need heat treated or anything like that? Also does it have a chisled shaped cutting edge or is it only beveled on one side? I'm gonna do some reading n reaserch of course, but trust many of the opinions of the craftsmen n historians on here.Any info would be great, Thanks guys for any help, YMHS Birdman
