I sent Kershaw an e-mail Monday explaining my issue with their Speed safe liner locks. This is the reply I received today:
After reading your e-mail - I can understand your frustration.
The Speedsafe mechanism requires the "front" washer to be somewhat smaller in diameter than our non-speedsafe knives. Also, the speedsafe torsion bar has a natural tendancy to torque the blade over slightly. To counter this we make the fit between the pivot shaft and blade pivot hole very tight. This helps hold the blade "straight" in the handle.
However - if the blade pivot screw is loose or the blade is used to pry with - the pivot shaft can be "tweaked" in some cases. This can enable the liner lock to move to the other side of the blade "ramp".
The Pivot shaft can be realigned simply by making sure the pivot screw is adjusted correctly (the blade actions smoothly and has no side-to-side movement). Then close the blade. Note - is the blade "leaning" ? if so - note the direction. Now - open the blade and put pressure on the blade in the same direction it was leaning in the closed position. BE CAREFUL not to cut yourself. You are re-aligning the pivot shaft.
Once done - check the pivot tension again - nice and "snug" ? - is the blade "leaning" in the closed position ? if so - repeat the process.
Now check your lock engagement - is the lock sliding to the other side of the blade ramp ?
This procedure may be necessary on these knives periodically if you require perfect lock position.
I hope this information helps and feel free to e-mail or call me if you need anything else.
Sincerely,
Craig Green.

but I won't razz him too much since he prolly doesn't check this forum much. The first time I met Ken he "tweaked" my Random Task - I thought he was going to break it in half!
