Why no thumb studs?

There is a Spyderco with both opening systems, thumbhole and thumbstuds, the Valloton Subhilt folder.
 
I just got my Persistence, and may I say, I SUCK at opening it. The only way I can successfully open in, it with a middle finger flip.

It also has vertical play, but I'm going to let it break it in, before I judge it.
 
Like mentioned earlier, I think that the spydie hole is MUCH easier to use with gloves on than any stud or disk.
 
my invention. extend the tang like in a friction folder, but it has a chamber which directs a small explosion and flips the blade open. not a switchblade, because there is no spring mechanism. The button might seem too far back at first, but that's to keep your hand father back so the explosive tang doesn't pinch it on opening...

edit: patent pending
 
All my knives have thumb holes but one. I got me 1 thumb stud knife just to experience it. The thumbstud works fine but it deploys less comfortable than the hole. My favorite combination is a thumb hole with axis lock, therefore new arrivals are all benchmades.
 
Hi Readyme,

When I was going through the process of inventing our opening hole, I went through a variety of "additions" to the blade and eventually evolved to "removing" something from the blade which I felt had advantages over the earlier methods I'd tried. (1980).

Our invention was actually ledge created on the blade that could be engaged by the flesh of the thumb. We selected a hole as a manifestation of that ledge. The round hole eveltually became known as a Spyderco and we were able to trademark the shape of the hole. As a trademark, it should be on every model and function cannot be part of a trademark.

Hi E1sbaer,

Welcome to the Spyderco forum.

Middle finger flick is awesome but some models have the lock side of the hole obscured which can make it hard.

Also, Spyderco uses a TON of backlocks which can't be flicked so it doesn't matter.

My Delica, Centofante, Caly Jr, and Calypso can all be flicked easily.

If it makes you feel any better-I got an Ambitious the other week and it had some friction and centering issues and then I got my blue persistence the other day and it is 98% perfect. It deploys quickly, Centered perfectly. All I did was switch the clip to blade up and scrape a few very minor edges of the g-10 to absolute flush with the frame and I'm good to go. I handsight-I should have sent the ambitious back but I am already 'invested' in its fine tuning and adj. So I'll keep both. (also-I now know that I am not interested in any spyderco thats bigger then the persistence. The ambitious is a perfect size for my edc needs. Hope the Y2 isn't too much longer then either.)good luck
