I've got one of those! Haven't worked with it much, but...one thing i did have to do was take it to get it professionally sharpened when I first got it. Not sure if it was supposed to be as dull as it was when it came out of the box.

It's supposed to be dull. Can't have the AF pilots cutting themselves.

The switchblade they issued back in the day was also dull, don't know anybody could ever get it to hold an edge. Only good thing on it was the hook blade for cutting parachute shroud lines.
