A microtome blade is used as part of a microtome in order to create very thin slices of specimens as part of the process of making microscope slides. This microtome blade is a wedge shape, although microtome blade can also have a planar concave shape or a chisel shape. This type of microtome blade would have to be manually re-sharpened in order to stay sharp enough to slice thin layers of specimens embedded in paraffin.

2016.zoo.12.2 Microtome blade: The blade has some rusting across the larger edge, as well as where the handle would be screwed in.
