The cutting action can be varied from a chopping to a long slicing action used for soft and fragile samples. The knife is made of very fine grained high carbon steel, enabling it to be sharpened to a very keen edge. The unique circular knife gives an extremely long cutting edge, reducing the number of times the blade needs changing and dramatically lowering the cost of re-sharpening. The blades are returned to RH Conservation Engineering for re-sharpening.
One blade is supplied with each RH Microtome in a secure storage/postage tin, additional knives can be supplied on request.
When fitted to the microtome, the knife is protected by a clear acrylic cover. Prior to cutting a section, the segment of the knife being used is revealed by raising a hinged portion of the cover furthest from the operator. The micro-advance on the RH Microtome is calibrated in 1 micrometre increments and offers an overall advance of 20 mm. The RH Microtome is supplied in a sturdy polished wooden case for storage and transport.
