The other knives you mentioned are assisted flippers, the 0801 is a manual flipper with KAI's KVT's bearing system. This combined with jimping on the flipper lever allows you to flip it open with as much authority as you want depending on how much pressure or force you put on the lever.
Why more companies don't put jimping on the lever is beyond me, it's the only jimping on the 0801 and works very well for flipping but also gives you forward resistance to your hand when the blade is deployed.
The full titanium handles have more grip on the blackwash then you think it would. It fits my hand perfectly, the ergonomics are excellent.
I have bought and sold over 200 knives including Spyderco, CRK's, etc and after a couple of weeks I'm comfortable enough now saying this is the best knife I have ever owned. If I could only keep 1 knife this would be it.
