Looks like the formula for Cutler’s Resin goes back a long way to the Neanderthal...Pine resin, a substrate like charcoal or even pulverized deer poop, and beeswax cooked together and used to fix blades and points to shafts and handles...Works and still in use today...

...I kind of like the Neanderthal theory. It was a particularly tough and dangerous world back then. These hunter-gatherers were stuck in the last blast of the Wurm glaciation that killed off so much of their food and so many species. It was every man for himself as they ran fearfully from—and ran hungrily after—woolly mammoths, sabre-tooth tigers, wolves, and other hominids. And yet elderly Neanderthal skeletons have been found in France with teeth worn down below gum level—and deeply crippled skeletons have been found too. Implication: They could only have been kept alive through the compassion of their communities and the brilliance of some nouvelle cuisine chef who could find food alternatives to incredibly indigestible plants, meat tougher than my old aunt’s shoes, and all of it cold. I try to put myself under the toque of that Stone Age Julia Child. I imagine him or her using bark to dip and carry water...putting food bits in it and noticing them soften or swell...marking how plants and berries, meat and marrow chunks would infuse the water with color and flavor. I imagine him or her getting the idea of warm broth from the 98.6 degree Fahrenheit mother’s milk that kept little Neanderthal babies happy.
