Both of these celts were found on Neolithic Swiss Lake sites in Switzerland. The celt at top was found on one of the Neolithic sites along Lake Cortaillod and the lower example was found on a site at Lake Neuchatel, Switzerland. Antler socketed celts, like the example at the top of this picture, are one of the most famous tool types found on Swiss lake dwelling sites. The antler sockets serve as shock absorbers to protect the handle from splitting. The lower celt measures 5 inches (12.7 cm) long.
