Swiss made. Originally used and hand forged by die sinkers, die makers, silversmiths, etc., in shapes and cross-sections appropriate to their work. Teeth are cut on small areas on each end (except the Hablis rifflers, which are single ended) and can have a variety of shapes. Rifflers are engineered for removing metal and smoothing in tight places. A long middle portion serves as the handle.
Precision rifflers, all are double-ended and 6" (152 mm) long.
