welcome to BF! You definitely picked a great knife in the 940-2.
I believe there may be some miscommunication in this thread. Flinging the knife open is commonly associated with users gripping the knife's handle and deploying the blade using centripetal force as generated by flicking the wrist. This method of opening a folding knife exerts a lot of unnecessary force on the knife and can lead to excessive wear and damage to the knife. Certain manufacturers even consider this to be abuse and such actions will void the warranty of their knives.
Even if you are not opening your knife in this specific manner, opening it in a way that puts undue stress on the knife's mechanisms can cause unnecessary wear, which can eventually lead to damaged parts and blade play. Using only the force necessary to open the knife normally will keep your knife in good condition for longer.
The lock stick you are mentioning is quite normal and will eventually work itself out with normal use of the knife. If you want to reduce its effect sooner, you can apply a very small amount of lubrication (KPL, Blue Lube, etc.) to the area where the AXIS bar rides along the liners. Keep in mind though that this will attract more pocket lint and dirt to collect here, so more frequent cleaning may be necessary.
I hope this helps and enjoy your new knife!
