If I didn't burn it? If I wrapped it in wax paper and threw it in the garbage? Maybe it cuts through the bag and injures someone handling it. Maybe an animal gets into the trash the and dies after getting cut by it. Turns into super steel? What the fuck are you even saying? It would take a razor blade many months to rust away if left completely exposed, and again I'm trying very specifically to avoid doing that because the blades are dangerous. I'm having trouble fathoming how you could be this dense.
