The blade will release sooner if pressure is applied as the corners of the bar/blade interface get near the edges. As for screws and monkeys; It is true that not all monkeys can or should use all tools . You are assuming that the lock bottoms out in the cavity in the blade and that is not the case. It is a wedge fit making contact front and rear but not at the bottom. So changing the depth of the lock by removing some portion of the total depth will not change the looks of the bar in the open position. The front portion (depth) likely will affect the closed bar height but that doesn't need to be removed to affect the release of the blade. It is also possible that reprofileing the cam portion of the blade would be the best option. Again, because it doesn't have screws, you can't fully assess the operation. If all of your Persions require the lock bar to be "fully" (or more) compressed then there would appear to be a design and/or manufacturing "issue".
No, I really wasn't assuming that but my last sentence was very poorly constructed that I can understand why you thought I did.. It really should have been split, because it contained two separate and totally disconnected thoughts. Let me try it again, with a bit of amplification.
Even if the Persian's construction allowed disassembly, I'd never monkey around with modifying lock engagement depth of it, or any Spyderco front lock knife. I know the lockbar on a Spyderco front lock does not "bottom out". I just believe they know more about lock design than I do, so I would not elect to mess with it.
I also feel very strongly that screw construction ruins the looks of a knife, and think it would be particularly offensive in the case of the Persian.
I hope that's clearer.
On the other hand, I would agree that on a knife with all screw construction, the issue could be solved. But the difference between us is that I would solve it by deepening the lock well, not by messing with the engagement surfaces. To me, that would be a much safer way to accomplish the desired result.
And yes, I agree it's a manufacturing issue. It's a result of the different depths to which the Boye dents are cut. In some cases, whoever cut them got a bit carried away.
