I return from multitool.org, bearing the Swissgrip and roaring my victory to the Gods themselves!!
I can't recall who directed me there in the first place, but whoever it was - thank you. I can now tell a Powerlock from a folding umbrella.
My oh my, this is one tough son of a Swiss. It's pretty much
pliers with a giant wood saw, full-size screwdriver set and a metal file. Just what I was looking for. It is perfect.
