I've been playing around drawing down the end of the tang of hidden tang knife, rounding the best I can on anvil then further rounding with files and then threading. It seems like it will be a great, simple connection. It doesn't seem like anyone does this. I did see a guy (trollsky) do it on you tube but everyone else seems to be brazing on lengths of threaded rod or other more complicated connections. What's wrong with just drawing down the tang, rounding and filing to size and threading? Thanks
