Hi, TrimTheKing
How can you plane a straight edge at an accurate constant angle? I can't, it's usually different angles down the edge often running out both ways, you need a strange shaped straight edge to hit all the places that are in the same plane, and if you could, just do it at 90 deg.
I still say that the sole is far to short to be of any use, it’s made redundant by practice and good technique, it’s a gimmick, a solution that has no problem, a waste of money, IMHO.

Hi Pete, okay, here's how I see it, before you even touch the edging plane you will have...
- a board (6"x1") with a reference face (the 6" bit, completely flat that you are happy with and have planed that way, either by hand or machine)
- you run this board, edge first (the 1" edge) through your jointer (or hand joint if that's your preference). You check this with a straight edge from end to end (ignore the fact that it could be <> 90degrees to the face at the moment) and see that you have a perfectly straight edge, it is straight from end to end down the 1" thickness.
- you now take the short soled edging plane, which has a 90degree fence built in to the casting, present the fence side to the reference face (6" part) of the board, press down to keep it flat and plane along the 1" edge.
You already know that the long thin edge is straight from end to end, now the edging plane ensures that it is also now square to the flat reference face. I don't see how the length of the sole would come into play here because the long thin edge is already straight, you are just squaring it up.
I don't claim to be right, but that certainly makes sense to me.

PS - I agree that good technique makes it redundant, and it is a gimmick, but I still think I understand how it works. The If the edge is SO far out of whack to affect a straight edge then even a blind man would be able to see that by eye
