This is a classic World War 2 era US Navy diver's knife, historically paired with the Mark V helmet. Produced by Morse Diving Equipment, this example features a brass sheath stamped "MFD BY MORSE DIVING EQUIPMENT CO. INC., BOSTON, MASS. U.S.A."
 
This example is in presentable condition. The wood handle and brass hardware are in very good original condition. The brass sheath is clearly stamped and in excellent condition. The stainless steel blade is sharp with all teeth intact. It does appear the fine edge of the knife has been sharpened in the past.
