jeffa, spot on the money there. I work with moving lights, where you have gears, springs and pulleys spinning around in a hot environment for hours at a time. The simpler the design, the better. I just don't trust little springs, period.
And what happens when the springs do fail? From my understanding, they are what keeps the blade in place on the Axis lock, pushing the lock bar against the tang. If you remove that pressure, what is the result?
The Axis has been in the field for about a year now, not nearly long enough to give it a proper analysis, yet Benchmade has already implemented it in several other designs because of the positive public response, and people seem to be clamoring for more. I myself am waiting for the 720 to come out to give the design a spin in the field.
