Alright, so I know this isn't technically a weapon, but it would be very usefull if the SHTF. I was wondering if anyone knew the best way to sharpen an axe. I've got a large and a handheld axe that are about 4 years old and have quite a bit of use. I've had 4 tall pines fall in that amount of time, and have used them to clear about 150 square yards of small trees, so they've had plenty of use and need a new edge. Any suggestions?
