Recently, a mechanic friend ask to borrow my (reasonably expensive) pocket knife. I asked him if he was going to cut something, or pry something. He said "pry." I handed him the micro-widgy.
I've also needed the micro-widgy a few other times in the last two weeks(...admittedly, though, I'm in the middle of a remodeling project.)
Cool little gadget. It's not one of those things that you need very often, but can be very handy when you do. I bought it primarily to save my knife blade. So far, it has.
