(Warning: discard the first section after cleaning the knife; it probably is a thick one.) When all sec- tioning is completed, xylene must be used to clean the knife; leave no corrosive ma- terial on its edoe. Section with an easy rhythm; never rush, or variable thickness of sections is likely to occur. As the sections move down on the knife they form a "ribbon," each section adhering to the one that precedes it as well as the one that follows it. During the cutting of the sections, a bit of heat is generated, enough to soften the paraffin and cause the indi-.
