Abstract

A microtome knife holder comprises a support element provided on the base connected to a microtome and at least one jaw for clamping the knife that is adjustable along a rail of the support element in the same direction as the cutting edge of the knife and releasably securable on said supporting element at a desired location. The guide means if formed of a prism rail of substantially dovetailed profile, a slotted foot portion of the holder is formed with a matching complementary profile and compressible by means of at least one screw engaging around said prism rail. Different holders, usually for different types of knives, can easily be slid on or off the rail. A quick release clamp and edge guard are also disclosed.
