Linerlock Questions

[SHostetler]

I need a little help with my linerlock folders. I've got 7 or 8 under my belt now and in general am satisfied with them except for 2 of them that have a lock that jams. On these 2 the lock bar jams and takes "excessive" force to open unlike the others. I generally wind up using a piece of plastic to pry the lock open. I've put graphite on the lock face and tried rapping the back of the blade on a piece of wood when open. Neither of these worked.

First question, what else can I try?

Second question, what can I do in the future the prevent this from happening?

Thanks,
Steve Hostetler

Make sure the tang is ground at 8 degrees.

Also, the lock bar should be around 0.040" thick where it bends or there's too much force.

Just a few ideas, hope it helps. :thumbup:

Just realized I forgot to include some info. The tang is ground to 8 degrees or as close as I could get and the liner material is .045 titanium.

Thanks

Have you overloaded the leaf spring? How far over does it go overwithout the blade in place? Is it more than the thickness of one washer and the blade? Even that can be more than enough. Frank.
