...good comments all. I understand that speed comes with practice, and after opening and closing my old style Spyderco 50/50 Endura about 20 times a day, daily, for the last 8 years, it's a pretty natural motion...
One of my buds at work calls it my 'ghost' knife, because you never really see it straight on, usually it's just out of the corner of your eye...and I close it one handed on my leg too...so it's a fast motion, and then it's gone...
That being said, I'm looking for a replacement, and I think the Speed-Safe knife in roughly the same size and weight of a Zytel Endura might do the trick...
The only concern would be accidental folding up under abusive prying, stabbing, cutting motions...that simply wouldn't do...
Also, I'm not to hip on safeties, firearms or knives, seems a little silly to me...(No flames here kids, it's how I feel...)
That being said, thanks again for the comments, and I'll look into the KO Kershaws I think.
