After reading the initial information of a second mass drop, I was sure I was going to pass. Was lucky to be included in the first one, no real need and also financially... But after getting more information, it is so tempting!! First heard about Xerxes 6 years ago and actually thought about ordering a knife back then. Prices were much less back then, but considering the kind of work he puts out now, this offer is hard to resist...The goal isn't to make a Kato clone - just that the grind will be Jannis' convex workhorse grind, which is similar to a Kato WH. The tip will have Jannis' signature aggressive distal taper, which to my knowledge is dissimilar to a kato, and the heel heights are taller than usual katos (at least for the 250).
I think Jannis knows what he's doing. Like you said, he won't make a knife that makes no sense.
