I emailed / PMed Joyce and Tazkristi - no response yet.
I checked with several dealers - all had wobbly blades.
If you don't mind, please keep us posted. I'm actually surprised Sal hasn't already commented on this matter, considering the large number of these that have been sold in a very short period of time, and the seemingly prevalent issues of loose pivots, off-centre blades, and warped blades. I suppose there's not much that can be done, short of exchanging all of the knives. However, since this is a new run of an older design and the "kinks" have yet to be worked out, I doubt that the replacement batch would be much better. My sympathies are with the dealers, who seem to be taking the majority of the fault by issuing exchanges and returns, when they themselves had nothing to do with the flaws.
