Loosening spring on lockbacks?

[fulloflead]

Has anyone ever found a way that works well to lighten the backspring on lockback knifes.

Say you had a Spyderco Endura or Police that you wanted to make easier to "Spidie-drop"?

Leave the knife half-open for 10 years?

By the time it wears significantly enough to loosen, it will probably be extremely fatigued and not have much of a life left, I would think.

Edit: But if it's brand new, it very well might go through some new-owned loosening. Just flick harder And, outside of the pinned Spydies, with knives you can take apart you could probably bend the spring a little.

Flitz rubbed/applied into the blade where it "rolls" around on the lock bar when opening and closing. Open and close it while watching the tube a few hundred times.

Clean as necessary and you should see a big difference in smoothness of operation.

My original Chinook required this over a few days of applications of Flitz and smoothed out very well.

You want tight springs on a lockback. That is what keeps it from closing on your fingers or coming open in your pocket. Your best bet is to use some polishing compound and work the blade a few hundred times. Then clean the blade and lubricate the rubbing surfaces with a little bit of candle wax. You just need to get better at Spydee dropping. I've use the technique on a lot stiffer knives like a Buck 110. The handle on those are so heavy that you have to worry about dropping or throwing the knife in the process.
