LOL I tried to hone a worn blade to make a true wedge once. Oh it was so close and I just had to try. The end result was, WTheck was I thinking :<0)

I have an 8" contact wheel and it covers most blade profiles you might call a wedge. If I had 250 bucks worth of cans I would buy a 10" wheel and I think that would just about cover everything made. There is a fellow that does double hollow grinds and I noticed a platen that had a rather large radius to it. I suppose that may be how a modern maker could get very near TRUE wedge.

If you go and look at the "how they were made" videos and pictures of the old shops you will see rather large wheels grinding away at the old razor blanks. The radius of today's razors are forged right into the blanks. That radius, no matter how large in diameter makes it possible to hone the darn thing. This is why you see pictures of 16 or 18" wheels with pedals attached to them. Guys made a living regrinding those old blades so they could be honed again.

Wedge is a term. A true wedge makes no sense at all. If you doubt me, go grind a piece of bar stock to a wedge and try to hone it. I dare you !
