Talking about the ByrdWrench in another thread got me to thinking about the fiddle factor in relation to tools. Some of the tools available seem to have just as much (or more) value for something to play with than as actual tools. So far, in my collection I have a few fiddle-y tools, and I was wondering what tools everyone else thought of that should be on the list, or which tools you are addicted to playing with.
Spyderwrench/ByrdWrench- I play with the whole thing, pliers, blade, taking it apart and putting it back together.
Leatherman Crunch- Open close, close open, open close, close open, and when I am feeling particularily festive, snap it in and out of the kydex sheath from On Scene Tactical
SOG Switch Plier- pretty well just snap it open, close it, snap it open, close it... occasionally squeeze my finger in it to test that the compound leverage is still there
Leatherman Surge/Wave/Charge- flicking the blades open and closed, occasionally rotating the tool and snapping open the other blade
Wenger Alinghi- opening the blade, pliers and marlin spike one handed over and over again, but you have to be careful with the Alinghi because the strong backspring will fire that plier handle into your fingers faster than you can cover that curse word so your three year old doesn't start saying it!
Victorinox Rescue Tool- opening and closing the main and rescue blades as well as the glass saw over and over again
ResQMe tool- don't do what I did and press the big black button at the bottom. Take my word for it, it's very unpleasant.
SOG PowerLock- floppy pliers are fun!
Gerber MP600- fun to flick the plier heads out over and over again!
That's about all I can think of off the top of my head. Any others have a high fiddle factor?
We should come up with a scale for this to include it in the Wiki!
