I bought my NOS 9/16 Wonderedge from Lynn Abrams (it got its first hone at the hands of the honemeister). It's definitely an interesting-shaving razor, I'll concur with the different feel of the delicate edge, and I'm not sure I really like that type of edge. I'm not sure my TI Egyptian is quite in the same league as the wonderedge, but then I'm not in the same league as Lynn hone-wise either so that may be it - this sucker is nearly as sharp as my Williams and that's saying something.
Heh, on first reading I thought you said it'd one-up the Wacker Like that's special.
