In the SCA there is a martial art called "thrown weapons" with involved 
throwing sharp objects (usually axes and knives but sometimes spears, I 
think atlatl is a separate category) at sections of tree trunk.  Cost 
is usually acquiring some weapons and help to scrounge and transport 
the butts (targets).  Check out your local chapter...  Map to find it 
at http://sca.org/geography/findsca.html

A couple years ago at Pennsic I discovered that axe throwers don't want 
their axes to be _too_ sharp, can't remember why.
