Pre-owned Tactical Folder Knife M marked Titanium/steel blade. $185.00 obo

This beast of a knife was in my late father's knife collection. I know absolutely nothing about it other than out of all the other folding knives my Dad owned this by far is the best well-made knife of them all! Don't have anything to weigh it on, but venture to guess it's close to a pound. I have never seen another production knife with as thick a blade as this one has. And locks up as if it's supposed to be used for space flight...

Only identifying marks on the knife is the "M" on the blade, and the pocket clip. I have no idea what its original value was.. So I'm pricing it accordingly.
