The longitudinal axis of each tooth is parallel to the longitudinal axis of each other tooth. Each tooth has a polygonal cross section shape such as in the form of a diamond. The cross sectional dimensions of each tooth enlarge from the free end of each tooth toward the base so that the spacing between adjacent teeth narrows toward the base. The facing edges of adjacent teeth interact with each other to capture, in a scissor-like manner, lice and nits therebetween. | |
