Not all authentic antique Yankee or Victorian-era scrimshawed images are on whale teeth. Walrus tusks were popular, as were (whale) panbone sections, sea turtle shells, and to a lesser extent, elephant ivory and hippo teeth. Here are a few examples of matrices other than whale teeth.
The first example is a (whale) panbone busk, custom-made for a form-flattening corset, which were required for Victorian-era women’s dresses. Each corset was equipt with several long, sewn-in pockets, designed to hold thin “stiffeners” (busks) often made of wood or baleen (fibrous material harvested from mouths of filter-feeding whales, often mis-labeled as whalebone). Whalers hand-made busks of ivory, panbone (whale jawbone), & baleen, for their sweethearts and wives. None would splinter like wood, and were lighter & stronger. Read more here
The second example is a sailor-scrimshawed, 23-inch x 19-inch x 7-inch, full sea turtle carapace (shell). There are eleven separate scenes, each on their own shell plate. There are two southern hemisphere birds at the top, and five northern hemisphere mammals at the bottom, each on their own panel. Down the center are six individual initials: four in English; one in Hebrew; and one in an Oriental script. I speculate that the six initials represent a six-man longboat crew, and that each man scribed the two images on the costal scutes (lateral shell plates) both sides of their initials. The bottom “tail” panel has a “T” the imposed on an “A”. I speculate that these are the initials of the captain’s name, or of the ship’s name. See more photos here
The third example shows the outer-curve side of a 13.5-inch & 22.8-ounce, Arctic whaler-scrimshawed walrus tusk, depicting silhouettes of: an Inuit mother & papoose in winter costume; a stretched sealskin boat; a loaded dogsled; a pair of igloos; and a skinning knife with an ulu (blubber knife).

The fourth example is a scribed elephant ivory billiard ball, which is also decorated with two ivory “ear” discs attached by brass pins. The compass rose is labeled with an “N” on one side, and decorated with a crudely scribed bark (ship) on the other. A date of 1841 is also visible just above left disc. The ball was drilled and tapped on the bottom, probably for mounting on a ship’s binnacle for decoration. See more photos here
Other forms of scrimshaw include jagging wheel pie crimpers, clothespins, bodkins, crochet needles, hand tools, knife handles etc. See more examples here.
