For a knife with one purpose for use by commando units, I thought the FS dagger was well-designed. Slim and light, could easily go through parts that really matter (the kidneys, the throat where you have the carotid, that triangle on the shoulder, the aorta and heart.) The round handle is admittedly unimaginative; more of copying whatever old dagger one sees (or imagines.) But this wasn't so big a problem, as one former commando explained. You almost always hold the dagger in a palm grip with the thumb pressing against the hilt. This will automatically "flat" the blade, even in the dark. In a frontal attack, you hit the left side of the enemy's throat with the blade vertical, then you twist 90 degrees and cut outwards to severe the carotid. Simple.
