Abstract
A histology radius blade grossing knife has a blade mounting system adapted to operatively retain a histology radius trimming blade. The blade mounting system provides a retaining spine for engaging an upper edge of the trimming blade, wherein a rear portion of the retaining spine is securely sandwiched by retaining plates of the blade mounting system. Furthermore, the trimming blade provides notches and/or recesses for facilitating such operative association. Each histology radius trimming blade embodies a radiused or otherwise uniquely shaped heel for cutting and dissecting tissue.
