ABSTRACT:
A knife holder for receiving wedge-shaped microtome knives, in particular regrindable hard metal or steel knives, has a base and upwardly open right and left clamping jaws for receiving the knife. The upwardly open configuration allows easier exchange of knives. The clamping jaws are mounted pivotably to the base to allow clearance angle adjustment of the cutting knife. Each clamping jaw has a clamping screw for securing the cutting knife in the clamping jaws. A height-adjustable knife rest is provided for supporting the back of the knife. A clamping plate is detachably positioned between the knife and the clamping screws, which clamping plate bridges the distance between the clamping jaws for stabilizing the cutting knife. The holder has at least one spring suspension for suspending the clamping plate to the clamping jaws. In the region between the two clamping jaws, the clamping plate has a tapering shaped lead-off section contiguous with the knife to form a virtually projection free plane so that the cut samples can slide off evenly.
