I carried my 110, SAKs, slippies, etc, in my pocket for years - I can carry anything clipless - and do. First item of business upon arriving home with my new knife - like yesterday with my new B-M 425 Gravitator - remove the clip. I stow the screws and clip in the original packages - just in case.
About the Benchmade screws... I've ruined a Craftsman US made T6 and two of the Torxx sets from Lowes removing them. Yesterday's screws were just as hard - until I heated them up, by placing the 'dry' (ie, wipe the hot tip free of solder with a rag!) tip of a 30 W soldering pencil in the Torxx head recess for 10 seconds or so. That breaks the blue Loctite B-M uses to secure the screws (They admitted to it's use in a call I made to them for more screws!). They will still be a tad stiff - but keep the downward pressure as you unscrew them.
I started removing Kershaws' clips years ago - then Spydie - put them in a ziploc bag - dumb move! Put them in the knive's packing.
I carry my Surefire E1b Backup clipped in my front pocket. I have bumped chairs, displays, car door frames, etc, and luckily heard it fall. The little beast is beat up - but I still have it 1.5 yr later. I don't carry open back folders unless they are in a pocket sock, sheath, etc - tired of pulling change out of the open backs! Of course, a knife is a tool to me - my legal protection is much louder.
