I have been known to throw a few axes around. Not in competition but just for fun at back yard functions.(well away from the kids of course) Any size can be thrown from what I gather. I have used the standard hardware store type Hatchet and Axe. If I remember correctly it was 7 paces for the hatchet and 9 paces for the axe. My target was a 3 ft dia. stump set up on a stand with rings painted on. The hatchet was easy to throw but the axe required using your whole body to generate enough steam. If your just learning, you may want to pick up a spare handle when you buy the axe.
