when should i greece the torsion bar?

[Legenda]

k. on my kershaw leek i can hear the torsion bar moving in the knife when i move the blade if i hold my ear up to the knife. does that mean it needs to be greeced? if i use it daily, like maybe open and close ten times a day, when should i greece it? thanks guys.

they usually have grease on the bar. if you can hear the torsion bar moving without holding it up to your ear then you might want to grease it but be careful taking the knife apart and have the blade open when you take the screws out.
