I got one a couple of years ago when they came out. One day I clipped it to the top of my winter boot, and I forgot about it. That evening or the next morning I flipped it open and it had tiny rust specks across the blade, from the humid saltiness of the boot. I cleaned it off, oiled it, and no prob since. Actually I forgot it in my car all winter and it was fine. It also went through the washer and dryer (not for long though with all that clanging) and it came out in good condition. It has sat oiled in a Maxpedition hip bag for the last year or so. She's a big bladed seemingly solid low cost folder. The big blade is easy to open and moves like butter.
