Where is the other diagram that goes from wedge = 1 to full hollow = 16 with all the diagrams??

Here it is:

Now IMHO I would say that ...

I through III would be Wedges
IV through V would be 1/4 Hollow
VI through VII or IX would be 1/2 Hollow
X through XII would be Full Hollow
and the last two would be Double Hollow

Is that about what most people here think?

Yes Bill, that is one of the diagrams. It appears that the wedge in that graphic is flat sided and the next one is referred to as a 1/4 hollow. Thats the rub, My perception of the 1/4 hollow is that the curve extends from the spine down to within either 1/4 or 1/8 of the edge. It is hard to tell. The other rub is that the Wedge that is shown seems to have no concave portion, yet some of the old english razors that I own do have the very slightest of concave to them that extends all the way to the edge. This is where the confusion comes from. Further on in the Arthur Boone document there is reference to a 1/4 bi-concave grind. So we have two 1/4 grinds according to Boone. One is a single concave that ends approx 1/4 above the edge ( same as the 1/2 hollow single concave) and one is a bi-concave grind. Boone also refers to a third 1/4 hollow grind. This is the result of the first grind made with a stone and the curve extends from the spine to the newly created edge.
So, within one document we have three different grinds that are all called the same thing, 1/4 hollow. Two of which are single concave and one is bi-concave.

Nice huh?

Randy, even the wedge on that pic has slight curve to it's sides, so it's not full wedge...

Bill,
I think it was Robert Heinlein that said Democracy in its pure form could never work because the masses would always vote themselves ice cream and circuses.

Ed (who keeps hoping that the unwashed masses will prove Heinlein wrong...one day)

Nenad, when I first looked at that graphic I had the same impression but the more that I look at it the less sure I am.
Perhaps my age is showing!
Any one have Arthur Boones email addy?
