I found this weapon inside my basement when cleaning out. It looks like a pen but is fully metal. It is activated by pushing on what would be the "Shirt clip" thing on a normal pen. It is difficult to load and the spike must be pushed against a solid surface. Says made in Italy on the clip. Has anyone seen one of these before? How old do you think this is? How rare do you think it is? How much would it sell for?
Sorry for quality. Camera phone.
