Does anyone have any info on the method of planing the underside of a cabinet top to impart a sense of both lightness and straightness. I've found a few Japanese youtubes where it is incorporated but not much written material. In one video the gentleman said that he used a special plane for this work and I am curious. I'm interested if there is a basic formula used to achieve this or if it is a "feel" for creating this edge. Also does edge grain/wood type play a large part?

I've made items incorporating various bevels and such but I'm looking for something much more understated. Thank you-
