I have owned 2 gerber multi tools.
They worked but could have been better
This one jammed up sometimes

This one was better and had the one hand open with wrist flick

I broke the file off on the second one using it as an improvised pry bar
Second one was best of the two.
I've never owned a leather man but have always heard them highly regarded by those who owned them
Bonus, this tool is the shit tho
