Improved lockback?

Oct 30, 2005
I've read about the problems concerning the simple lockback knives failing due to insufficient lock engagement.

I've been thinking that this could be rectified by using a stop-pin, as on a linerlock, to position the blade.

This would allow a better geometry for the lock, as it would only function as a lock versus the dual functions of lock and positioner.

It would expose the lock to fouling by debrie, however.

Any thoughts?

I am just glad that the march of progress allowed me to move away from the lockback for anything more than casual use. Not that it was Buck's or Spyderco's fault, but I have had each fail to engage from disappointingly small pieces of pocket lint or other debris. I have never had either of those particular problems with liners or axis locks.

Locks fail. That's what they are designed to do ... close. That's why some knives have dual systems, like the MOD CQD with a thumb ramp lock in addition to the actually reliable button lock, the LAWKS system on CRKT knives, and the crossbolt safety on Extrema Ratio lockbacks.

Maintenance, maintenance! Ya gotta keep your equipment clean! :D

Interesting idea, and I'd love to see what you do with it.

However, I'm with boats. Modern locks, like the axis and compression lock, are not only at least as strong (and notably more reliable), but much, much easier to open and close. The compression lock is especially maintanence free. I have no desire to return to the lockback. Especially having one fail me before.

The real lasting plus of the lockback is in aesthetics. The lockback, in my opinion, interferes least with the design of the knife. You have to reposition things and open things up for liner locks/compression locks and axisesque locks, plus you get to see those things. Not so with the lockback.
