Could very well be a hinge rivet that has come out of the plastic. Fairly common problem.

Been out of the loop for a while, saw this thread and have a few comments. I have tried the quads ( Thanks JR ) and initially asked about how the different radii were "blended". Never got much of an answer so being a part time machinist I mounted a Quad 1 up in the mill and swept it. On my blades you could pick up the transitions to the different radii but the change was so subtle I can't believe even the best skater's would be able to feel it. I'm talking numbers is the .002 to .004 inch range spread over about .500 to .700 length of blade. My GUESS is the new profile is continuously varying with the subtle transitions gone. I'd bet in blind taste tests about 3 out of a hundred skaters could tell it apart. I've been wrong before!!! Dave
