Not my mind! (LOL.) My Manix 2 (G-10) ! Seriously : I was climbing in and out of rental trucks while helping some friends move yesterday, so I was worried that my knife would fall out of my pocket. I found myself periodically (and neurotically) checking that it was still there by placing my hand upon my pocket. I know that the clip is fairly secure while attached to the pocket, but the knife could still become caught upon something such as a seatbelt and fall out - unbeknownst to me. I'm thinking about attaching a lanyard to my knife and securing the bitter end to my belt loop during strenuous activity such has hiking and scrambling.
Anyone else here suffer from OCD regarding loosening a knife?
