Hand Planes by Kunz Germany. Once you try a Kunz Pench plane, you'll want another one. There's something very different and easy about them. Their mass, balance, fit, feel and useability are on another level. You can adjust the mouth opening with a single screw. They seem to combine features of traditional bench planes, with a little innovation. The casting is stress-relieved annealed grey-cast iron, the iron is tool steel hardened to 60-62 HRC and seated to prevent chattering. The sole is precision ground, and the sides are square to the sole. Made in Germany.
