[QUOTE=mrsell63;1490905]Here is a J Rodgers wedge from well back into the 1800s. I laid a 6 inch hook rule across the width of the blade. There is about .025" of air space under the rule which makes the blade just about a full wedge.

Yes, that sliver of light makes it a "near wedge" not a "true wedge". Oth it is what people generally, but technically wrongly, refer to as a wedge.
