Would Spyderco ever design a folder with thumbstuds?

I used to prefer thumbstuds, but after using a Spyderco, I'm completely sold on thumbholes. I even got my Mini Grip with a hole instead of a stud.

You can't spydie drop a knife with thumbstuds.

I was "Spydie dropping" a Buck 110 five years before there was a Spyderco knife.

I've cut myself pretty bad trying to Spydie drop my SAK.

Knives have holes where the pivot is (obviously)... you should be just as "worried" about that hole as any other hole.

As a structural engineer I can tell you that the state of stress at the pivot hole is considerably different from what it is at the thumb hole. Plus the typical Spyderco blade is much thinner at the thumb hole. But from what I have read and what I have reasoned, and depending on how you are prying, your biggest problem is tip breakage and not breakage at the pivot. If you make a prybar that tapers uniformly from a point at one end to its thickest at the other end, stick the pointed end into an opening and start prying with it, the maximum stress will always be near the tip.

Striders have opening holes (albeit not round) and they're still considered prybars.

It also depends on how the blade is shaped and how thick the blade is above and below the hole. A FFG Spyderco will have a relatively thin blade beneath the hole, especially a model like the Mil or PM which has a relatively large hole. It also depends on the shape of the blade before and after the hole, for instance the PM2 hole is high in the blade and the material that goes over the hole has to dip down behind the hole to form the thumb ramp so it is not really in line with the blade tang to be fully efficient in transferring bending stresses past the hole.

Knives aren't for prying. Mini Ti pry bars aren't that heavy nor big, get one.

I am very cautious about prying with any knife so this is the best solution. Of course emergencies can happen maybe you only have the one knife with you at the time.

You can try, just make sure you're wearing some steel-toed boots

A little off topic, but what's a spydie drop?

Gripping the blade (usually by the Spyderhole) and snapping the handle down to open the knife.

Thanks, now I know what to call it.
