For those that really want to know about liner and framelock philosophy I advise getting hold of Bob Terzulas book on the Tactical Folder. He discusses in great detail what should be done in order for a good reliable lock. To sum up: There are many variations in the recipe, but the core ingredients have to be kept.
Strider chose for a smaller contact surface, whereas others might chose for larger contact surface such as Chris Reeve. Both are correct as they do not go beyond the limitations of the lock, IE to little or too much. Angle of engagement, materials used are probably some the most important aspects, to much angle and the lock will slip, to little the lock will jam and can also slip. Get the book, read, it is worth it IMO if you are serious about trying to understand a lock that some see as "simple" but is actual far from it to do it properly.
