you aren't supposed to like the feeling.
So I guess I pass the test all the time then??? I would love to see a video of this done properly if anyone has a camera around and is willing to do a fail/pass video.
One thing I've noticed with the three finger test (which I use ALL the time), is that the more often you do it, the less scared you become. This, of course allows you to do the test more properly, but it can also lead to slicing a couple layers into the tips of your fingers. I've noticed lately, when I do it, when I'm all finished up, I have very fine lines cut into my fingers, but not anywhere deep enough to draw blood.
Basically, just pay attention to what you're doing and you'll be fine, as long as you you don't mind the odd mark.
With the Three-Finger-Test, how do you know that you're not feeling a wire? Also, I remember a while ago, Dave suggesting that the TFT doesn't work with very refined 'slick' edges.
