Fettling knives are used to trim the pour hole waste and to remove mold marks from cast greenware. They are also useful for many trimming, carving, and sculpting tasks. The soft steel blade may be bent as desired, while the hard-tempered blade has the spring-like feel of conventional knife blades. The blade is 4-1/2 inches long and is set in a smooth wooden handle for a total length of 8 inches.
