My thumb keeps slipping from the whole on the spyderco knife....
I think this problem happens with knives that have strong detents and then super easy action? At least that's what happened with mine -- I had to press my thumb into it kind of hard to get it open, and then it practically flew half-open and the blade's edge got ahead of my thumb, and then my thumb hit the edge. If that's the case for you, you might try a knife that has a more even opening resistance, or even a knife which can be opened by other means (such as a flipper tab).
First and foremost: Welcome to the forum, Alicia!
This is a problem I´ve never heard of or thought about, I could not even really picture it till embrys description.
But now I think I understand.
Alicia, perhaps you could post a short clip of what is happening? For example via streamable.com?
Anyway it would help to know which exact knife you´re talking about, what your hand size is and if this is your very first folder with an opening hole.
Does this happen to you even when you open the knfie slowly (so not flicking the blade out)?
Have you tried any other Spyderco / knife with an opening hole, for example when trying out Spydies in a store?
Differently (but with all respect) to "the Mastiff" I think loosing or tightening the pivot a bit is something you could try. But if you are new to Spyderco before that it would be good to know which knife it is, so we can tell you the size of the pivot screw and point you towards using the correct tool for working on it.
