I've found that a small machete and a SAK is most all I need under most camping/hiking activity. This one, made by my dad when I was a kid is still one of my favorites, out of my 12 inch Ontarios and Tramontina's. He made it out of a regular size English machete he picked up just after WW2. Abrasive wheel and lots of coolant running on the blade. It goes through a hardwood 2 inch sapling in two to three chops, but weighs very little.
I love small machetes!
