Thanked: 59Yes, sorry for the confusion. I should have made that two separate line items.
Grind: Near wedge. I'm going to be grinding it with a contact wheel so it will have a bit of an arc to it (not completely flat). My goal with this is to replicate a large stone wheel grinder.
Thickness: Thick enough that it could be honed laying flat with two or three layers of tape. I don't want it so thin that I am trying to "free hand" the angle.

Thanked: 59I've been perusing the stub tail pictures. This grind is kind of appealing to me. It doesn't go all the way back to the spine, which would allow for a thinner piece of steel.

Thanked: 59From another thread on this forum. I'm placing them here as reference for this project.

Thanked: 3222OK, now you are talking a razor with a tapering width blade so the spine thickness varies to accommodate the varying widths of the blade is all. The old way of measuring blade width was not from the top of the spine but from where the spine contacts the hone. That might make a difference when calculating. What is above that contact point is irrelevant to the geometry calculation.

Thanked: 59Correct. I measure where the hone contacts the spine, not the top of the spine. Tapering the thickness of the spine from the toe to the tail would allow for a varied blade width and still maintain the proper edge bevel. The more I look at these, the more appreciation I have for them. They may look "plain", but a lot of thought went into these things.

I think this is a better explanation.

Thanked: 3222Yes, you are describing a near wedge and not a true wedge of which there are very few. When I said size it is the same as width of a razor measured from where the spine contacts the hone to the apex of the edge. You shouldn't have to free hand the angle if you go with what Bruno told you a few years ago about width to thickness ratios. The geometry to get near a 17 degree bevel angle should be the same for a near wedge as for a full hollow, the widths being the same for both, only you remove less steel from the blade in making a near wedge. The bevels might possibly be wider on the near wedge.
