What have you done to the knife to remove the lock? Asking because I wanted to modify one Outrider aswell for some holiday trips but dropped it.
I carefully removed the slide lock side scale, with a thin guitar pick.
I then removed the lock guts--all straight forward.
I filled the hole with a few layers of paper cut to the flat dimensions of area, with a few drops of super glue on each layer.
Near the top, I filled in with more super glue until level more or less.
I sanded down the glue until even with the scale.
On my blue-scaled Helmsman, I melted in some blue plastic laundry line near the top, before sealing with super glue.
On my Rucksack, I cut a piece of unglazed ceramic to fit, and sealed it with super glue.
Our laws allow blades up to 10cm, non-locking, no questions asked (unless you are threatening someone). The 111mm Vic line works out well, with the lock removed. As said, I was 60 years old before I even held a locking folder, and I have cut myself far more since buying locking blades. I grew up with a variety of slip-joint pocket knives, up to SwissChamp size. I used the saws and blades quite a bit in making walking sticks. For most uses, the lock is not as critical as many imagine. Heavy or repetitive work, yes, the lock helps. I am not speaking of any "survival" or "tactical" uses of course.
Test the spring before removing the lock! Some models have weak backsprings because of the lock. Hold the slide button in the disengage position, and open and close the blade to check.
For some models, like the WorkChamp, I have both the now-deactivated slide lock, and the new liner lock model. Camping, hiking, home use, etc. the lock is fine. In truth I have never been searched by the police, even with a fixed blade hanging in a sheath from my belt.
