The Warther should be interesting. They now use CPM S35VN which is not a bad knife steel from what I understand. And there are not too many wa conversions of that knife out there. We'll see how that works in the kitchen.
The koa handle on the Carter slicer is an earlier version of the one I made for Bao - I messed this one up, sanded it too thin and then actually broke through the side wall. It was just a very small hole, but then I poked around and it bcame a huge one I filled it with koa dust and epoxy, but you can see it, I just didn't know how to emulate the pattern of the koa with my filling. I was going to throw it away, but the koa and the horn are both so nice tat I decided to keep it - and the Carter was the only knife that was a match in size.
The black one with the kukui tip and the slim koa one with the mammoth endcap just came out very slim and I was wondering what to do with them, but for the ultra slim Moritka slicer and the thin fuguhiki they should work great.
