Something that I spent a lot of time on many years ago was the ability to throw a knife (or pretty much anything with a point on it) with both hands. It took a while to get good at it but I would say I passed from horrible to passable in a pretty short period of time. I still break out my bag of "throwing implements" - everything from knives to nails to axes - every once in a while to see if the skill is still there. One Saturday we'll have to get everyone together for another projectile weapon crash course. Until then, enjoy The Great Throwdini!
