I would take the axis lock over a liner lock , for strength and saftey alone . Both Spyderco and Benchmade make linerlocks very well , bottom line I dont care for liners in anything but small folders . I look at the liner as a slipjoint with a retard mechanism . Benchmade makes a pretty good production framelock , Spyderco makes very good , strong lockbacks . Choosing is next to impossible , both are good lines , both have their followings .
