History and Durability
The Mark 3 features a 61⁄2" 440 stainless steel blade. It has a saw tooth back and a black oxide finish, with high impact plastic handle and sheath. The original had a steep counter curved point which the Navy requested be reinforced because of damage to the tip of the blade when prying. They have since reinforced the tip eliminating the reverse curve making the point more sturdy. People have found many uses for this knife, including using the butt as a hammer and the blade as a prybar which may cause personal harm. The blade is said to hold a great edge and be very durable.
