The new guppy! It was the first in the invention line and is absolutely safe to take on aircraft or the like. No sharp edges but it will serve you well when you need to defend yourself. It has edges do grab soft tissue, acts like a great hammer with a “bonk” on the head or boney areas of the body and the small point at the bottom of the handle goes well in soft tissue plus pressure points. Can disarm weapons too! Its a great tool if you are nervous carrying other things through check points or where they have metal detectors; it’s plastic so won’t set them off.
