The US Navy Standard Dive Knife, a stalwart piece of nautical equipment, boasts a well-defined look. However, during the 1930s and World War II, the Vince Forge Company of Easton, Pennsylvania, delivered a unique variation. These Vince-made knives for the US government stand out for their distinct features.
 
Two key elements set Vince knives apart. The most striking is the swivel ring at the handle's end, a helpful addition absent from standard specifications and unseen in other manufacturers' knives. Vince also implemented a different sawtooth configuration, with 13 teeth per inch compared to the standard 12. 
 
While the exact reason for Vince's deviations remains unknown, surviving examples suggest they received smaller contracts during the war mobilization for equipment. Today, collectors of vintage diving gear consider the Vince knife, especially with the intact swivel ring, among the top three most challenging World War II dive knives to acquire.
 
This particular Vince knife is in good original condition. The varnished maple handle features some wear from use. The brass sheath exhibits a nice patina. The Vince blade shows subtle signs of use from decades past. The unique swivel loop is intact. It appears the loop was repaired long ago. If you are looking for a key addition to your knife collection or an impressive piece to display next to your helmet, this would be an excellent choice!
