How do you use your thumbstud or hole?

I was told it can actually damage the tang or stop pins by slamming them open. I haven't seen this personally but it makes some sense in theory. I assume it would take a long time, abuse, or inferior materials/quality to happen.

I heard the same thing
 
I think that's probably true for the people that whip them open with their whole arm like a maniac, and maybe even harsh wrist flicking, but I really doubt flicking them open with just your thumb like I do is going to cause any damage.
 
I basically flick all my knives out including my spydercos. I have pretty much done it since I got my first knife with a thumbstub many years ago and it just grew on me. I dont put all the force I can into it but I do just enough to get it open and I havent seen any damage to any of my knives so far. If you practice enough you can flick any knife open except maby ones like a SAK or Buck 110.
 
On my Spydies with the larger holes(14mm?) I use my index finger and "point" the blade halfway open and use a slight move of the wrist to finish "soft-flicking" it into place. This is also advantageous because I carry them tip-up most of the time and the index finger naturally moves toward the spyderhole when drawing the knife from my back pocket. I was able to use this kind of opening on my old CRKT Crawford/Kasper Pro because there was a similar amount of space between the thumbstuds and the handle to allow it. I wish more knives with thumbstuds had such a wide space/a more generous choil. As a result, I'm a bit biased against them as of late, particularly with the Kershaw Leek and BM 710(good as all its other qualities may be).
