I've " lost" one off customs for a while, and found them again (an XL J. OESER that he and I designed together) lost that one 4 times, for a week or more at a time....
I've "lost" many GEC and eventually found them.
Still looking for my Spyderco Delica that I put some where safe (but not in my safe....lol) before I went to the beach...
It is the worst!
