Okay... I know this is an extremely dead topic (2 years), but i see most if not all the posters are still active members... Im surprised none of you mentioned something obvious...
I have two hands, and most of these have handles!!!
You could hold handles back to back, for a free hand to open doors, or, if strong enough legs... Start kicking down doors!!!
Now if a zombie apocalypse then sure two would get heavy... So in the end might have to use one as a weapon.
But my choice, since my collection is new, and small, if i had to pick one, would be my 1st gen Trc-931. But if i could manage the two, id also throw in my dirty nasty unrestored M70.
