I've read comments around the web that brazing was not an unusual historical construction method for blunt weapons. Assuming this is true, it would seem to me that brazing provided acceptable strength, especially for the rigors of combat. My questions are thus: does anyone here have experience with brazed parts on impact tools? And would a copper braze survive hardening?
I recently forge-brazed a spike to a small hammer (clean, flush joint, C-clamped together, wound with copper wire, brought to red heat in non-oxidizing fire and fluxed, etc). The clearance is under .005". It's not hardened or hafted yet but I've thrown it against a wall a few times without breakage. That's not the level of abuse it would suffer as a backyard basher (its intended purpose), though. I just want to hear from others before I spend any more time on this.
