An instrument for the precise trimming of flat or cylindrical embedded specimens to be sectioned in an ultramicrotome is described. It will produce the required truncated pyramid accurately by hand slicing. A simple modification to the LKB specimen holder allows it to be used with the Reichert ultramicrotome as well.
