The Denman Pin-Tail comb (8.5") is used for parting and sectioning the hair. The comb and tail portions work together simultaneously in your hand as you part, section and comb the hair. Pin tail combs are excellent when working with wet hair. Use the tail to part and make sections during a roller set, then you can conveniently flip the comb to comb the section of hair. A metal pin tail comb is suitable for foil highlighting as well as sectioning.
