I have not read that articel, but I doubt that your information is correct. A 12deg low angle block plane with a 25 deg beveled blade = 37 deg for the cutting angle. Most bench planes have have 45 deg which is equivalent to a standard block plane where the bedding angle is 20 deg.

: There is an article in the November/December 2000 issue of Wooden Boat by the
: eminent planer Aime Fraser. Interesting, she explains that a low-angle
: block plane actually has a higher cutting angle than a standard bench
: plane. The reasoning is that a block plane is used with the blade bevel
: up, so that the cutting angle is the sum of the blade angle in the plane
: and the angle of the sharpened bevel. In a bench plane the bevel is down,
: so the cutting angle is equal to the angle of the blade in the plane.
