Rockspyder, I have a WB from Strider that from memory will easily outcut the folder NIB. After the work I did on the folder I would assume that it would outcut the WB in its NIB status. I will do a direct comparison between those two shortly.
M, integral locks have the same inherent problem. They have however one thing that makes them more stable. When you put a side torque on an integral the liner will tend to move just as it wants to with a liner, however with the integral you are exerting a force in opposition assuming you are squeezing the folder tightly.
The last part is critial, when I was doing the lock work on the Buck/Strider it did not require a *very* tight grip to exert the forces necessary to cause the lock to disengage. I don't think that the compression I was exerting would have been enough to force the liner back into place on an integral lock.
The solution then is to simply keep a very tight grip, overly so even, on integral lock during such use. This will insure that the liner stays in full contact with the tang of the blade and thus the only way for the lock to fail is for you to compress the face of the liner or snap it is half. Both of which should require considerable amount of force.
I should note that what I just said about Integral locks is not based on 100% exeperience. I have used a couple lightly and how they responded seemed to indicate the above. However I could not repeat what I did with the Strider on them as I didn't/don't own them and the possible for damage is highly likely.
It is also critical to note that as Joe says, it is possible to build stable liner locks. However it is *very* difficult to figure out who makes them. I have not tried many, Spydero, Buck/Strider and a few cheap ones, but the inherent instability as compared to a simple lockback really screams out to me as a glaring flaw. Comparing the lockbacks from the same people in every case gives a much more stable lock. You basically have to break them apart to get them to release.
Lenny, there are details of the drop point folders in both the Buck and Strider forums. I cannot remember any mention of chisel ground blades.
