I still want one of those 10/8's. I think It's Joesph Elliot that made them, but don't quite remember. Jimmy has one IIRC.
Joseph Elliot, Joseph Rodgers, and Wostenholm are the ones that come to mind for me that I have seen. I have a 19/16 Wosty, but not quite there. None of them $500 blades IMO though.
