Abstract
A knife holder for a microtome has actuating levers for fastening or for releasing the knife on the knife holder, constructed such that in the position effecting the fastening of the knife, the actuating levers extend at least partially over the cutting edge of the knife. The actuating levers thereby act simultaneously as finger protectors and prevent inadvertent contact with the cutting edge in the side regions of the knife when the knife is fastened. The fastening of the knife takes place by means of permanent magnets, which are arranged in the base portion of the knife holder and motion-coupled to the actuating levers which cover the knife edge.
