Having just finished a course in knife combatives, I have to offer this up.
Several people had fixed blades, most of us had folders. For speed, surety, length of strike, strength, and even concealment the fixed blades have it all.
Saw a Gerber Applegate 3/4 Fixed, several Polkowski/Kasper fighters, and one or two others. Folders were mostly Benchmade AFCK's, with two Crawford/Kasper folders, and one Emerson COmmander. Most problematic knife was the Commander, it was mine I might add. Opened to soon, or not completely enough. This caused some bleeding (very sharp edge) when trying to draw too fast. Biggest problem was my inability to consistently open the knife as designed, on the pocket seam. I resorted to standard folder opening, using the snaproll after it had left the pocket.
I am considering going back with a fixed blade soon so I can learn to use it correctly. Oh by the way, a flat fixed blade of about 5-6 inches is VERY concealable even on a 5'-2" women of petite build. Folders in the pocket are always visible.
Just some thoughts!
