From what I've found, car springs are made out of 5160, carbon-chromium steel,
and is considered as high carbon (but not as high as others?). Is there a better
steel for throwing knives that could feasibly be scavenged out of a dump? Also,
I was interested in the question of balance: which is better for a throwing
knife? Center-balanced, handle-heavy, or blade-heavy? Speed is important, if
that helps.
