I have the Gerber MP400, the plier head slides into the tool locking it closed.
I love it except that the pliers do not have a spring to open them selves when loosen your grip.
The only 3 I have yet not broken is my SOG PowerAssist, the Shrade Multi tool, and the Buck Tool...

I don't think they make the Buck Tool anymore through...
