My SAK is always with me. I have carried one since I was a kid. First was stolen in Africa, by a safari mate. That was it. Its replacement was bought at a fair outside Tucson, a few months after that. Some thirty years later, it's still going strong. It has come in handy, it has fixed the (seemingly) un-fixable, innumerable times. Victorinox did replace the key chain holder, about fifteen years ago, at no charge to me. An actual Swiss army guy cleaned the knife for me when I gave him a lift from a campsite and let him crash at my place for a night. He said he couldn't stand to see one that was not spotless. That was about twenty years ago. I do a better job cleaning it, now. The Swiss army guy would approve, I think.
