Buy your smoother which will be in the neighborhood of 70 mm and maybe even one you keep for rough work, complete. But then get a Dai blank and separate blade and make your own kanna. It's very good practice all laid out well in Odate's book. I have always wanted to try a kanna smaller than the smoothers, closer to 50 mm. You'll maybe want the bottom conditioner to go along with them.
