Well, sometimes you just need to stick up for yourself. This crustacean, clearly in fear of being someones next meal, grabbed a hold of knife and attempted to ward of any harm that may come to him.
The video is gaining quite a bit of traction on the web and for good reason. It is a rather entertaining 36 seconds! The crab truly looks as though he knows what he/she is doing. Every time a human hand tries to go near, the knife is swung in a furry of anger backed with a protective notion!
