Seems like everytime I pull my boat out I'd forget the chip in the mast base. Loose it everytime. Except coming back from S. Padre one made it 1400 miles home. I buy em by the fist full, loose some, misplace others, actually wear out two a year and buy about 15. I've lost at least 2 Leathermans from leaving em on the tramp. Poor luck, or poor attentiveness to where I leave my stuff.
