No safe queens here either. While I certainly have more than I actually need (~30 folders, ~20 fixed blades), I still try to use them all. There are a number in EDC roation, and although some haven't seen pocket time for awhile, every one has been carried and used at some point (including rarer ones like my first production BM 630 Skirmish and my Kershaw Ti JYD 2). I stash others in various places around the house where I might need one, and still others get stuck in bags and stuff like BOB, hunting, fishing, or camping gear so they're always there if needed (or if someone else possibly forgets one). I have all of TWO knives in my safe which have never been used (both SRKW Chopweilers), and one will be getting sold really soon for that reason. It is the same wrt guns for me. I don't have the money to be throwing away on something I will not use. If I see something as an investment, maybe, but that would be my only reason for a safe queen.
