What are the benefits of lockback vs. liner lock and vice versa?
Liner locks (Crater and Expanse 33-models) are quicker and easier to open, unlock, and close with one hand. The lockback system (Crater and Expanse 55-models) is generally stronger than the liner lock system, and is considered more traditional since it has been around for so long. It typically takes two hands and when working with a larger blade in the case of the models Leatherman uses the lock back system on, this is an added safety measure.
