With a 7 ft (2.1 m) primary regulator hose you need something on the right waist strap to hold the hose down in place. Otherwise, it floats around and gets in your way. Sticking the hose under a cutting device sheath in the middle of the waist strap doesn't really work. I suppose you could mount a second cutting device sheath on the right side, but it would be hard to reach with your left hand.Or a cutting instrument which tends to be more useful. It does not have to be on the right waist strap.
