Retractable Trick Dagger

When produced and used quickly in conjunction with a bursting blood bag, simply a thin polythene bag filled with blood fluid and then heat sealed and taped to the part of the body to be stabbed, it makes a spectacular impression. This is an 18cm long piece with a black handle, into which the silver blade retracts when stabbed against a solid object.  Please note, it doesn’t retract or move when used with a slashing motion.
