Loctite vs Not?

[VashHash]

I use loc tite or more commonly Teflon tape now. I actually had the screw for the lockbar on my P4 work it's way out. Luckily I caught it before it came out completely. If you do any kind of flicking or inertia based openings I highly recommend something to keep the screws in.

Blue stick for loose screws. If they came loose once, they probably will again.

I use blue Loctite on clip screws, but haven’t yet seen a need to use it on pivots or body screws.

Blue Loctite - yup

[kennethsime]

Yes.

I had a pivot screw on a N5 LW disappear and have several knives from different factories come with loose screws. So my answer is blue locktite and have recently become a fan of the stick.

Blue loctite, always.

Often I even apply one right when I receive a Seki knife, cause some had body-, clip and one time even the pivot screw come loose and fall out after a short period of use and carry.

Agreed. I had a pivot screw lost on a salt 2 when clipped to my swim suit in El Salvador. After this I checked all my other seki salt knives which needed loctite as well. While this seems less common with Taiwan spydies, I also had a very loose pivot on my Caribbean right out of the box.

In my experience, blue loctite is often crucial. When tightening the pivot on many knives, if you tighten it to the point where the screw is secure, the action is extremely stiff. Finding that sweet spot to avoid play and still have good action requires a little loctite to keep the pivot from loosening up.

I use blue tube loctite but not 100% of the time. It really depends on the clips and scales I'm swapping. If the knife is still breaking in then I'll go without a thread locker but one it's been used and I don't plan to disassemble for some time I do use loctite.
