Abstract: A callous plane 1 having a blade head 2 and a handle 3 is disclosed, where callous plane 1 has an underside facing the body surface of a user when in working position, and an upper side facing away from said underside, and where a holding device 4 with a lower holding part 7 and an upper holding part 9 is provided in the blade head 2, in which a blade 5 can be held in such a manner that its cutting edge 6 intended for use to shave off callous skin is located on the underside of callous plane 1. To provide a callous plane 1 that is safer and easier to handle, and less complex to manufacture, it is proposed that lower holding part 7 be connected to handle 3 and display an upward-pointing seat 8 for blade 5, and that upper holding part 9 hold blade 5 tightly in seat 8 with the help of a fixing device.
