Has anybody checked out the kershaw zing and other flippers

[Tuffblade]

ive noticed a lot of kershaw flipper models have larger flippers, large enough that i think if you hold it in a regular grip your index finger could serve as a guard for the knife folding on you, potentially making the knife very strong, as you might have a little blister on your finger instead of a bone deep cut, could be a new knife design sort of like the extrema ratio

also anybody have any experience with kershaws liner and framelocks, i generally dont like them but who knows, i could be turned a believer, like lock strength etc

any thoughts
