Axis Lock Fragile?

[loonybin]

Given the fact that the patent has expired for the axis lock, anything could be in the mix, including having that coil spring show up in newer models. I own a Manix 2 and it's a very solid knife without play of any kind. Who knows?

There's no question it's solid. My only problem is that the lock is so stiff that it was forming callouses on my index finger and thumb on my left hand -- the same fingers I hold coronary wires 0.014" dia. with. Not good! If it weren't for that, I would have kept it.
