Are you talking about knapping from a flint nodule or sharpening a gun flint? Can't help with the nodule, but if it's sharpening a gunflint, here's a little brass one. The head is only 1 1/8 inches long.
Pete, that is a very fine set. Particularly admire the scrolling and twist on the vent pick, as well as the ram's horn on the hammer. Did you make the chain as well?
Yes the chain i made by flattening some binding wire around, then bend the flat wire around tips of serclip pliers in a figure eight before cutting the links with a chisel.
