Between these two limit cases, the correct knife angle must be deter-
mined. A clearance angle between facet angle and block surface of
approx. 5° is normal.

AUTION
!
Different microtome producer use different scaling for their clearance
angle adjustment, resulting from different calculation bases. The clear-
ance angle might refer to the facet surface or to the angle between knife
main surface and block surface. As the facet has a divergence from the
knife main surface of approx. 5°, the resulting difference is approx. 5°.
Therefore, set the correct angle on Thermo Scientific Microm
