Grossing forks are designed for hollow organs or specimens with layers and are available in 3 sizes: 1.5 mm, 2 mm, and 2.5 mm. Each fork has 2 sets of tines—the distance between the tines determines the size of the fork. Grossing forks hold the tissue in place while sliding a trimming or scalpel blade against the outer surfaces of the fork, resulting in a section of the desired thickness between the tines.
