I see a sibling rivalry brewing!
This could be good!
But there's only ONE way to find out!
Dunno who'd be crazy enough to try it though..
It would have to be a timed sheet metal chop-out event.. 2 users.. 2 knives.. rest.. then switch maybe.. average the 2 times.
Could even simulate the upside-down / cramped environment.. keeping it safe of course: goggles, gloves, etc.
A good way to put a new knife on the map.. go challenge a legend.
