I actually just gave up on the thumbstud, (because of getting nicked, and also because it was a hassle for me to get my thumb tip against the stud). I just use the finger flipper thingy, instead.
Right....
Here's what I wrote way back almost 3 years ago -

Action -
The Speed-Safe assisted opening is fast - perhaps not as fast as the much smaller Chive, or Scallion - but it's marginal - it feels and seems fast.
One of the great features of the latest series of Kershaw/Ken Onion Speed-Safe knives is the Index-Open - which kind of looks like a trigger that protudes from the back of the knife when closed - using the index finger to press/pull back on this overcomes the initial resistance of the mechanism - thereby activating the torsion spring bar to make the blade open. When the knife is open that Index-Open acts as a finger guard. Very clever and works very well.
Index Open
The knife also has ambidextrous opening thumb-studs - but although I can work this fairly well - since I have used Speed-Safe knives since they first came out some 3 years ago - I find that the thumb-stud requires a slightly modified technique when compared to a straight unassisted/manual liner or frame lock, and may not suit everyone.
To open one has to push the stud outwards - away from the handle - and when the blade starts to open - get the thumb out of the way - it's not as complex, or difficult as it sounds - but it is not the same as opening a manual liner lock......
But it is different enough, that in the early days Kershaw demo knives at first had a plastic guard covering the blade toward the heel, and later had UNsharpened blades, because some people did not get their thumbs out of the way fast enough, or used the "follow through" as if opening an unassisted/manual liner lock, and have nicked themselves.
So why the thumnb-studs - when the Index-Open works so well? - is this a case of "belt and braces/suspenders"?
No..... the ambidextrous thumb-studs are actually the Stop-bar to stop the blade against the handle.
If one examines the knife open - one can see that the thumb-studs are flush/hard against the handle and there is no stop-bar on the back of the handle that stops the blade's back heel - as in a traditional unassisted/manual liner or frame-lock.
