The locking action is similar to an axis lock, but I'd say the tactile feel of the axis lock is much nicer. It feels weighty and solid, yet smooth.
The lock on this knife just feels like a spring loaded button that you pull back to unlock. Kind of light and insubstantial feeling compared to the axis. It also lacks that satisfying heavy click that you get from the axis lock as the blade snaps open.
But I have no doubt that this lock is solid, none-the-less. I have no worries when I use mine, and I've never heard on this type of lock failing.
