Your requirements were similar to mine when I purchased this knife.
5500 Details | Benchmade
I don't know if you saw the link on the page for the knife you cited, but it explains the lock function. Locking Mechanisms | Benchmade
I find the quality of the knife to be the best I've ever owned. I paid about $170 at Mark's Outdoors in Birmingham, AL.
Opening and closing work smoothly and safely. The button is not pressed, it is pulled/slid back, withdrawing the bolt from the detent on blade allowing the spring mechanism to push the blade open. The safety blocks the bolt from moving out of the detent, you literally cannot pull the bolt back.
I hope this is of some help.
