It was not just anyone who could make a flint dagger like the Hindsgavl Dagger. It was a very specialized craft, superior to anything that had been seen before, and required a master of the art! The secret behind the sophisticated daggers was the use of the so-called ‘soft technique’. By striking the flint directly with a soft hammer of antler or hard wood, one could make a crude initial form of the flint object. Afterwards a small flaking tool could be pressed on to the surface of the dagger to remove small oblong flint flakes.
