So I'm onto building snipes bill planes and I really can't find much information on them. I guess my first question is on the shape of the iron. Is the iron the same shape as the sole, both concave and convex portions or just the concave portion. Also I heard there is supposed to be a small flat at the point. Is the sole flat at the very point or does it come to a sharp point and the flat is produce because the iron sticks out somewhat on the escarpment side, like a rabbit does?
