1. Queen Country Cousin - Lost for about six months in my brother's Jeep, showed up with slightly marked up handles and a small rust spot, but otherwise held up just fine. The D2 didn't even noticeably patina.
2. AG Russel 3" Titanium Lockback - Fell out of my watch pocket at some point, never found it.
3. Kershaw Chive - One of my first knives, moved out and left it at the house.
4. Kershaw Junkyard Dog - Clip got caught on the couch, found it a week later wedged in the cushions
I think those are all the knives I've lost.
