I clip my work knife in my back pocket that is on the far side distal. It's in a good spot that doesn't interfere with sitting.

Yeah it's uncomfortable as hell to sit with anything in back pockets. I've actually utilized this at work. My customers often have me sign out contractor keys that I must return before leaving. Keeping them in a back pocket prevents me from driving away with them. I'll know as soon as I sit down if I didn't return them

My folding boxcutter has a belt clip and I hang my Gerber Dime on a suspension clip. Both live at the top of my rear pockets. I never sit on them.
