I have a Buck Rush 290 and I’ve had it for about 3 years now. I keep it in my pocket so it potentially has a bit of lint in the mechanism. The assisted opening has been slowing down significantly and most times won’t open all the way until it locks unless I push it the extra distance manually. What’s the best way to go about oiling this knife so it will perform the way it originally did? I didn’t want to disassemble it without proper instructions for fear of not being able to put it back together correctly.
