Buck sirus problem!!

[Orthos]

The problem is that the main screw is getting loose. i tighten it but after a few days it gets loose and the blade leans to the right (also the blade is shaky in the handle).

Is there a way i can permanently tighten the screw because this is really irritating.

Loctite is cool! Though few can spell it....

Be careful which one you use though. If you use the blue Locktite you shouldn't have any trouble taking the knife apart again if you need to sometime in the future. The red Locktite is much tougher and may make it very difficult to take the knife apart again.
