Buy another and be on your way.

Ahh, but be careful on this, true that cranks are hardened...in certain places such as journal surfaces to certain depths. The entire crank is not and cannot be hardened completely, it would shatter quickly if that were the case since cranks actually do flex back and forth at the rod journals with each combustion cycle from the sudden explosive forces, and hardened steel is very brittle, unable to absorb that. As to whether or not the snout is hardened, I don't know for sure, but have my doubts since it is not a heavy load wear surface as a bearing journal would be.
