Spyderco Liner lock tension adjustment

[Himalayan]

I recently bought a Spyderco Tenacious which has a liner lock. I put in a couple micro drops of oil and adjusted the pivot screw just slightly to where the pivot tension on the blade is just right when the liner lock is depressed. However, when opening and closing the blade the detent ball friction seems stronger than it needs to be. Is there some way to decrease the liner lock tension without risking making it too loose?

I´ll suggest you´ll take it apart and clean it properly, relube and assemble. Most often the problem is solved that way. Manufaturing residue is probably what causes the grittyness or friction.

If I hold the liner lock fully depressed, the blade moves smoothly and freely and I adjusted the pivot screw to be not too loose or too tight. When opening, the tension on the blade is from the strong pressure of the liner and detent ball pressing on it. It works as it should but seems stronger than it needs to be, making opening with a thumb flick more difficult than it should be. I was thinking that the liner "spring" could be "tuned" slightly when the knife is disassembled. But that could risk ending up with insufficient pressure to fully engage the liner lock. I have no experience doing this - I'm just wondering if this kind of adjustment is ever done. I have many liner lock knives that deploy way easier than this one.

Let the knife break in naturally.

I have had problems in the past disassembling a Spyderco due to their locktite and soft fasteners. If you decide to disassemble then be aware of how you do it and try to avoid having to send it back to Spyderco for repair. They are not a company that promotes their customers to disassemble a knife like say CRK or Hinderer.

Yes, I've followed those discussions online. Regarding disassembly, Spyderco has listened to the criticism and they've stopped using red loctite and now use only blue. All the Spyderco knives I have I've bought recently and have had no trouble at all in disassembly.
