A haul of Stone Age artifacts included a highly ornamental deer antler that had been turned into an ax handle. By “back in the day,” we mean around 5500 B.C., of course—the period in which a recently discovered antler was used in a variety of ways. Archaeologists discovered the antler within a Stone Age settlement, noting both its ornamental carvings and its use first as the handle for a battle ax, and later as a harpoon. “It is clear, though, that this ornamentation was carried out with a thin cutting edge,” Larsson wrote. “Subsequently, the ax was broken and transformed into another tool, probably a harpoon, which eventually also became fragmented,” Larsson wrote.
