This modern knapped  knife was made in Flint River flint, and it was hafted on a handle of our local Occoquan River driftwood(species unknown). The full knife measures 7 and 3/4th inches long. Stone knives are ideal for several traditional/primitive chores, but must be treated differently than steel knives. They can cut hide and fiber well, but are not used aggressively to chop, pry, or carve wood.  The softer sections of the driftwood handle was stabilized with some modern epoxy, and the transition between handle and blade was set into the wood with a pine pitch/charcoal mix glue/gap filler mastic, and the exposed flint blade section measures about 3 and a half inches long.
