This always baffles me. It's not just the Launch series.Before this thead gets moved, or closed, the Launch series can be dangerous knives. I have a 1 and a 3.....when deployed they lock up about half the time. The spring doesn't apply tension for the entire length of travel. The blade 'bounces' back and doesn't lock up. If attention isn't paid to make sure blade is locked.....could get ugly.
