1. A measuring device (40) for characterizing a shape of a surface of an item, the measuring device comprising:
a frame comprising a holding frame (44);
a first set of three or more probes (41a-41j) movably held in the holding frame, each of the probes having a respective probe end (43a-43j) for contacting the surface of the item; and
electronic sensing means configured to provide for each of the probes a respective electrical signal representative of a position of the probe relative to the holding frame,
wherein the device is further configured to cause determination of an unevenness signal representative of an unevenness of the surface, the unevenness signal being representative of an angle between 1) a straight line through the probe end of a first probe of the first set of probes and the probe end of a second probe of the first set of probes and 2) a straight line through the probe end of the second probe and the probe end of a third probe of the first set of probes.
