I really just dug this up from looking at the canopies on the choppers. Strong thick tip with an angled down double swedge (spey) - could aid direct penetration into the canopy seal if need be. Big a$$ rounded pommel to palm and pry with. With flight gloves, I tried the thumb grooves on a CRK Mountaineer and it was as if they were not there, so the larger ones should soak up the glove better.
I agree on the pomell, it needs to be thinned or stretched out a bit to relieve possible pinch. Need to maintain that big pommel however.
This in a 5" 3/16" or even 1/4" blade would be awesome. Like I said in the other thread, nylon sheath to hold a G2 or similar that can be used while sitting and stil in sheath to read leg pad info etc.
Bring it!
