Abstract
The knife comprises a block (1) with a front face (3) in which a diamond blade (9) with a frontal surface (10) which is preferably coplanar with the front face (3), is held. The diamond blade (9) has a back surface (11) forming a cutting edge (12) together with the frontal surface (10). A plastic insert (14), preferably of epoxy resin, adjoins the back surface (11) spaced from the cutting edge (12). The insert (14) has a plane upper surface (15) whose plane intersects the frontal surface (10) at an angle of 80.degree. to 87.degree., preferably about 84.degree.. Thereby sectioning and section pick-up under a stereo microscope are facilitated.
