I have been lurking on this website for many years now, but I've finally made something that I think looks good enough to show off. I made this as a Christmas gift for my wife. It ended up being far bigger than I had intended, and I think I could make version 2 a lot better because of what I learned with this one. The blade is 3.875" in diameter and about .197" thick at the center with a hollow grind. that I made by clamping a grinder with a flap disk in a milling vise with the blade in the spindle. I'm not going to admit what that blade steel is, but I will take any advise on what to use for a replacement.
