A comb includes a hollow frame having a pair of fixed teeth at opposite ends thereof, and a cap having a depending body portion disposed within the hollow interior of the frame. A series of transversely extending open slots in one longitudinally extending side planar face of the body portion receives individually a series of axially rotatable rod-like teeth. Each one of the open slots is four-sided in cross-sectional shape, and the fourth side is open in the plane of the face. The depth of the slots is greater than the thickness of the teeth so that the teeth fit entirely within the slots. In one embodiment of the present invention, the teeth are made by rotating axially rod stock and moving a cutter having the configuration of the desired shape of the teeth into cutting engagement with the rod stock. In another embodiment of the present invention, the teeth are formed from rod stock placed in a cavity having the shape of the body portion of the teeth to be formed, and then moving a die axially into engagement with one end of the rod stock to cause the rod stock to flow into the shape of the desired tooth.
