They are forged, groimd and tempered with exceeding care, and while some slight variation is to be expected as to relative hardness and thickness in different knives, they are all within the limits for satisfactorj- section cutting and sharpening. Our method of grinding these knives provides that the cutting edge and the edge of the back lie in exactly the same plane, a very important featiu-e in the longer knives when used obliquely as in celloidin sectioning, and also in sharpening. ISIost difficulties in satisfactory section cutting are due to the condition of the knife edge because of unskilled attempts at sharpening. A microtome knife is usually considered to be unfit for use if it will not easily clip a human hair held by one end, and for many kinds of work even this is not a satisfactory guarantee of The cutting edge of a knife can also be easily examined under a low power on the microscope stage, and when it has been properl}- sharpened the edge will be seen to be smooth and even. 7182.

The original form of knife designed for use with all Sliding "Sledge' Microtomes. In this type of knife, the chief difficulty has arisen in the past through the fact that the lower surface of the shank has not always been found to lie in the same plane as both the cutting and the back edge. This feature is carefully observed in the manufacture of these knives. Length of blade, mm 90 125 165 Length of cutting edge
