Air Force and their stealth airplanes aren't all that new an idea. For the past few years the number of stealth wrenches has increased tremendously. Lay it down, five seconds later and it is gone! Haven't taken two steps, and it just isn't there at all. Look for two days, and it decloaks, is laying in a previously empty spot. Had a few stealth screwdrivers but haven't seen them come back for some time. Even had a stealth chain saw one time. Put it in the shop after firewood season, then needed to trim a limb, it was so gone that I must of had a visitor. Even went in the shop at night with a strong flashlight, checked under things, behind boxes, nothing, no sign at all. Went to the same pawnshop I bought the first one, got a near twin to it, as I knew the kinks of that model. Used it as is, carried it to the shop and tripped over something sticking out from under the drill press. First saw reappeared, right where I had been walking for weeks. Had cobwebs, so I knew no one had swiped it, must of been hiding in some dusty corner while it was cloaked. I'd like to sell some of these stealth wrenches, get em out of the shop, but can't lay my hand on any at the present.
