Burdock root is hard, narrow, and round — awkward to cut by hand. The PROGRADE Kinpira Peeler creates strips at exactly the right thickness of 3 mm : thin enough to cook quickly and absorb the sweet soy glaze, thick enough to maintain satisfying crunch. The blade spacing is specifically calibrated for kinpira-style cuts — slightly wider than julienne, narrower than standard strips. This precision separates authentic kinpira from rough approximation.
