C.S. Osborne No. 498 8 Prong Thonging Chisels
C.S. Osborne 8 prong thonging chisels punch a straight row of evenly spaced slits for leather lacing and thonging in a single strike. Choose 3/32" or 1/8" prongs to match the width of your lace, both at one price. Strike them with a rawhide mallet over a cutting board for clean slits. See Lacing Tools for lacing needles and supplies.
