Often people ask “what is the knife Navy SEALs use?”. The short answer is- whatever knife they want/purchase to carry. Most of the time in the military this is a decision based on personal preference or choice. However, most military personnel get issued a knife/bayonet/multi-tool based on their MOS (Military Occupational Specialty) or basically “job”. The Mk 3 MOD 0 Diving/Survival knife manufactured by Ontario Knife company happens to be the SEALs issue knife during BUD/S. This knife is also used by Reconnaissance Marines at the Combatant Divers Course in Panama City, Florida.
The Mk 3 MOD 0 was designed primarily to be used as a tool and this is evident by the features of the knife. There is a striking butt that can be used for hammering, a serrated saw edge on the spine, as well the ability to pry with the thickness of the blade. The knife also features a clip point with a very up-swept tip. Since this is an issued knife used for diving; I believe they chose 440 Stainless Steel for two reasons. One being somewhat corrosive resistant and the other being it's a cost-effective metal to mass produce. Another benefit would be the simplicity of sharpening in the field. The Black Oxide finish would also facilitate in protecting the blade from rusting.
Comes with original sheath, has some sheath marks, otherwise excellent condition.
