Threadlocker is great for knives with screws that have the propensity to come loose, especially butterfly knives.

Inexpensive. Does its job keeping screws from backing out. Good stuff.
Keeps your knife from falling apart.
I typically don't use too much threadlocker. This stuff is nice and cheap so it's good to use when you need to. Very few of my knives actually need it but it's nice to have on hand.
