Checkering is nothing more than a textured surface of cross-hatch pattern of parallel lines that intersect each other. The intersecting grooves running, at an angle to each other, creates a series of pointed diamond shapes, called points. Checkering is defined in lines per inch (LPI). The higher the LPI, the finer the pattern will be. Fewer lines per inch result in deeper grooves and a coarser pattern. There are several types and techniques used in checkering. Checkering can be found on stoppers and barrels or both.
Carved calls are hand carved using traditional hand held tools such as knives, gouges, files, and sandpaper. Any wood can be carved, but they all have different qualities and characteristics. The choice will depend on the requirements of carving being done. For example: a detailed figure would need a wood with a fine grain and very little figure (as strong figure can interfere with fine detail).
Scrimshaw is the name given to scrollwork, engravings, and carvings in the form of pictures and lettering on the surface of the bone or tooth, with the engraving highlighted using a pigment. Common modern materials include: micarta, ivory (elephant, fossil, and walrus), hippo tusk, warthog ivory, buffalo horn, giraffe bone, mother of pearl, and camel bone.
These calls are manufactured by binding or fixing the strands, particles, fibers, or veneers or boards of wood, together with adhesives, to form a composite material.
