I bought a caly 3 couple weeks ago, and I have a little tiny bit of blade play. I can move the blade up and down just a tiny bit. Since the handle has rivets, I can't tighten it up to possibly get rid of the play. Any suggestions on how to fix this and also will this get worse over time? I think the amount of play stayed the same, but now it seems easier to move the blade up and down. For such a highly praised knife, I was a bit surprised. This is the g10 caly3 btw.
