USN MK3 dive knife made by Ontario in the US, original black plastic scabbard; great overall condition. This type was used by USN Seals in 1975-2000.

The official US Navy “Mark 3, Model 0” dive knife manufactured circa 1980th in the US by Ontario Knife Company. This type was in service from 1975 till early 2000th and in use by the USN SEAL teams in the field. This is a well-made and practical knife; it’s the perfect size and weight for what it was designed for. The knife is a bit used but it’s in great overall condition; certainly 100% serviceable still.

The blade and the heavy-duty hammer-like pommel are 400 stainless with black iron oxide for the added rust-resistance. The handle is molded black plastic – it’s in excellent shape with no cracks or chips; all parts are tight with no play. The knife is about 10-3/4″ / 27.3 cm overall; the blade is about 5-7/8″ / 15 cm long. Ricasso is marked MK 3 / MOD 0 on one side, 2V376 on the other. The blade has been re-sharpened and it’s razor-sharp still; the tip is intact; sat teeth on the spine could use some re-sharpening. Original USN MK3 MOD 0 molded black plastic scabbard with nylon webbing and brass wire belt hanger. The scabbard in in great condition as well and holds the blade tight.

This original USN MK3 dive knife is in excellent overall condition; it is 100% serviceable still. Not cleaned or tampered with in any way, 100% original “as is” condition.  I have a few more Vietnam War fighting knives and bayonets, as well as several scarce WW1 and WW2 American and European fighting daggers, bayonets and trench knives available for sale – please take a look in our Militaria section.
