well i am not sure if i said it, but about one of the only power tools i have is a drill, but in no means a great one. i have not done any hardness test yet, as i figured a finished blade like this is already hardened pretty good, but i am sure i could be wrong. if there is a way to drill through it, then thats what i want to do, but i think someone said something about annealing first, and i had a hard time finding too much out about this. the tang is tapered on both sides from about 3/4" wide to about 1/2" wide at the bottom, and is 5/16" thick. I don't really understand the thong hole thing, seems to me like if it were to ever be needed, it would swing and cut me rather than fly across the woods, but thats me. if i can drill it, then i will put some pins right through for strength? thanks for the patience.
