Almar lock problem

[Huncroc]

The blade moves back during a cut. meanwhile the lock who jumps.
Spyderco I did not see one like this. Is this a wrong lock?

Thank you for the answer.

Another badly fitted lockback looks like. Contact Al Mar and I'm sure they'll take care of you - two different lockback issues in one day from Al Mar and Spyderco, weird.

The lock is not engaging properly. It could be something as simple as dirt or lint in the lock well of the blade or under the lockbar inside the knife, or it could be a poor fit. Clean the knife thoroughly, use a toothpick to reach all the hard to reach corners. If that doesn't help, contact the maker.

Thanks for you
The lock clear, something else the mistake. I write to the manufacturer...
