Yeah, so…during one story arc, Peter Parker got reborn with extra powers including organic webbing and wrist spikes (as well as a couple of other things). Eventually, he lost these and went back to his original powers.
Well, the writers decided to recycle these powers and gave them to Kaine when Kaine's character got revamped for Scarlet Spider. One of those things being this spike that comes out of his wrist that he can stab people with ala Assassin's Creed's hidden blade.
