The Flint Knapping Hammer is the original multi tool of the 18th Century! Our hand made knapping hammers are all individually hand forged with each one being unique from the next. The design is based off of original period pieces, with a knapping “hammer” on one end and a turnscrew on the other. They do an excellent job of providing the right tool to maintain and knap your gun flint or perform any necessary adjustments or screw removal while out in the field. They’re very handy, measuring approximately 3 1/2″ long, making them the perfect addition to your kit.
