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.

I would first get all of the lint out of it that I could. Then I’d give it a shot of WD-40, wipe it off real good and test it out. If it still doesn’t work then pour a shot of liquid plumber on it to dissolve the lint, back to step one….. have fun….
Try soaking it in a solvent such as paint thinner and then brushing it clean with a tiny brush (shaver cleaner brush?). Then oil it lightly with a sewing machine or gun oil and wipe of any excess.
Cave creek has your answer!—NO WD40– wd 40 should not be used for oiling anything, I don`t understand why people think this is oil! WD stands for water dispersement! I works for things that are rusted, to loosen, but afterwards they need oil! Sewing machine oil is great oil,it actually seeps upwards.
Use hot soapy water and a tooth brush and scrub it down, and rinse out. If you soak it down in oils or solvents you may have a problem getting it all out. Could leave oil stain in pants.
