I can only say that I have never experienced any of these things in roughly +20yrs of using a pick. ...and I'm very curious as to how you used a pick that may have separated the tip from the ferrule...? The idea is to push down into the surface top surface (dome), not into the side of the tip. ..and definitely not to use a prying motion, if that's the case.Very important because that outer edge is where the roughness needs to be. With the pik, it's very easy to weaken the sides, leading to tears/cracking and eventual separation from the ferrule.
