Thumb-Holes....

[T.K.C.]

I just use my thumb with a thumb hole.

Here is a good example of how to open a knife with a hole in the blade.

I can't say I like his closing method though, it's a little too risky for me.

Especially given the one handed closing method that's mentioned in the MANUAL. Spydies have a choil such that if you put your index finger at the top of the grip, the choil will hit your finger and prevent the blade from closing further. I use this to close the knife against my leg.

I EDC an Endura that I bought this summer. I open it the same way as that guy, just slower.

It really doesn't take much downward pressure on the blade. In fact, if you push too hard downward, you'll torque the pivot point and make it harder to open. Push out, not down.

I too am a thumb stud to thumb hole convert. Now I find thumb studs uncomfortable, even on good knives.

My last knife was a CRKT M16-13z, and I mainly used the thumb stud to CLOSE the blade. I replaced it with the Endura because I wasn't satisfied with the edge retention of the cheaper steel in the zytel models, but I loved the knife otherwise. I like the Carson Flipper better than thumb holes, but they aren't very sheeple friendly.

Of course, YMMV. It's not like there's something WRONG with you if you prefer thumb studs. There's a reason they're still on the market after all.

What is choil and sheeple?

 

[yablanowitz]

Choil in this instance refers to a finger choil, a hollow for your index finger to rest in. Many Spyderco knives have a finger choil which is half on the handle and half on the blade, called a 50/50 choil. Basically, it gives a smooth, flat surface on the part of the blade that would contact the finger when closing the knife.

"Sheeple" is our own derogitory term for the people who act like sheep - scared to death of a two inch pocketknife. Also known as NKP or Non-Knife People.

This one is easy to solve...Get yourself a Kershaw Cyclone. It has a "Speed-Safe" AO which opens the blade for you with just a slight push on either the "flipper" (on the upper spine of the handle), or one of the dual thumb-studs.

Soooooo to complete your thought here as regards the original question can we assume you mean to use the flipper or thumb stud to open the Cyclone and use some part of that to access the Spyderco hole? Or do you mean to use the Cyclone to chamfer the edge of the Spyderco hole to make it more comfortable and the Cyclone even more unusable? Inquiring minds want to know!

I use the thumb hole by using the flesh of my thumb and pressing down and away, or I'll put the tip of my thumb in and press out and away. I prefer a thumbstud, though. If, no when, I order a Griptilian, I'm sure I'll want the thumbstud model.
