The MK 3 features a 6 1/2" blade with a black oxide fininsh and molded high impact plastic handle with sheath. The Navy Knife measures 10 3/4" overall.
I have owned this knife for ever. It holds a good edge , not sure what the blade material is - i have read its 440 SS , nothing more specific than that. The blade is thick for prying. I would never use it for that but its thick enough to out pry most combat tactical knives even though its technically a dive knife. The saw on top is ok, it has a saw edge on the very top and then at a slight angle and wider going down the side. May be good for under water rope ??? The flat blunt butt of the knife provides a solid smack to whatever your applying it to. The handle is good, fatter in the middle and can be held firmly with force but i think its not as good as more modern stuff in term of feeling "grippy" when moist. it is however one of the toughest handles i have seen. The sheath is good but very thick at least an inch and it has metal that hold the knife in place - its a piece of springy metal pushing against the blade. its not the best choice because it rubs against the blade and makes noise when drawing it but it is secure. you would have to flick it about full speed to eject the knife from the sheath. The best part !! the point, a bit too pointy for some people (gets pretty thin)it will puncture with ease thick leather or canvas. Over all this is the best quality knife i have in term of durability and toughness.
