Omg, And your saying your liner lock will still function with sand an crap in the lock where as the axis won't?:barf:
Funny, really, i have had liners cease to operate with sand an crap in them aswell, same conditions that would foul a axis or compression aswell.
If its a tool, and it is. Maintain it, atleast enough to keep it in working condition, but if your too lazy to do that, a fixed blade maybe better for you.
If crap an crud impairs an axis lock, it surely will hinder any other aswell in the same conditions., ya dont think that liner needs room to move back an forth to operate or what lol.
Usually, a non heavily oiled axis will let the crap fall right through an not trap it like your liner lock, even a Lockback can be semi self cleaning in this aspect, where as your liner fails miserably and traps the crap.
