Stupid injury... what to do?

You might want to clean around the edges. I don't know what the silver stuff is but you don't want it to cause an infection. It might be residue of what you were cutting on. You could use some perioxide if it's too tender to touch. Then, yes, I would put neosporin on it with a band-aid until it gets scabed over then I would take the bandage off and let it air out and heal. Be careful and try not to break it open so you don't get an infection in it. Sorry this happened to you.
