I have an old one made by some old timer.  I got it about 35 years ago when  I was just a kid at an antique and crafts market.  Back when there was still good stuff at those things.  Don't know anything more about it other than it has been used a lot since I have had it and is still going strong. However, I my Gerber brush thinner machete does most of the work I need done around the house, in  camp and out in the  field.

Definitely need 'em when hunting the (pound for pound) toughest animal in the woods...squirrels....little bugger take a LOT of killing!

I had to pop a raccoon with one once (my wife always gives me a metric ton of poopie about this story)...I was out chasing Mr. Bushytail....leaning up against a tree....next thing I know a PISSED off boar coon was coming down the tree to show me who was king of the forest.  Gave him a rushed shot and he kept on coming and I had to go to more primitive methods...hence the hawk.

Check out the custom Hawks by Straitshot in the Sponsor Classifieds. They look pretty fantastic.
I think it's just a hobby for him, but it looks like he knows what he's doing.
