In you original message you did say "aggressively flick open". You now seem to be backing off that. So which is it? What is the need to open it aggressively?
I think it is probably none of our concern why he does whatever he does.
Cajun93: Give your knife time to break-in. Many titanium liner/framelocks are sticky when new.
Make sure the lock-face and lock-tang are clean. You can use an acetone/alcohol soaked Q-tip to clean the lock-tang. The lock-face is tricky to clean without disassembly. I stick a piece of paper between the lock and the tang and let it lock-up, then pull the paper out. Do that until the paper comes out clean.
Once everything is clean you can put permanent marker or pencil on the lock-tang. Try both.
About flicking causing damage; every movement of the knife is causing damage. The more energetic the movement, the more damaging.
Enjoy your knife.
