You have some skills being able to throw small shovels. I have throwing knives, been doing it for almost 9 years. Not to toot my own horn but I can throw knives in almost any hand configuration and body position.
My brother and I have a mutual fascination with knife throwing. We have a few knives we throw in my backyard against wooden boards and such.
I even saw a pretty cool knife throwing movie called 'Girl on the Bridge'. It is a foreign french movie with english subtitles that I caught on an independent movie channel awhile ago.
Damn, this thread has made me think about this as a hobby. I have been practicing with my slingshot, it's a cheapie, but there are some nasty ones out there. I want to make some contact explosive pellets for the wristrocket. Not sure how to go about it, though.
Anyway, picking up some knives soon to give it a shot!
Peace
