The rarest and arguably the most desirable Mark V knife is presented here - the anti-magnetic Fischer Spring! These knives were used by divers working around underwater mines set to explode via magnetic attraction - like a ship's hull. Made of beryllium, brass, and wood, these were made in limited numbers by Fischer Spring. With their distinctive gold looking blade, these are the holy grail of Mark V knife collecting! 
 
The knife appears to be new old stock - aka never used. The brass hardware, wood handle, and beryllium blade are in like new condition. There is a leather belt loop on the brass sheath that is also in excellent condition. 
 
Fischer Spring N.Y. and the mil-spec number C-713051 are clearly stamped on one side of the beryllium blade. Do not pass up this rare opportunity to own the most difficult and desirable Mark V knife made!
