Heavy War Hammer from Russia or Poland Klevet or Chekan 16th Century

A good Horsemans Warhammer and pick, originating from Russia or Eastern Europe, known variously as Nadziak, Klevet or Chekan. Related to the European Warhammer, and developed specifically for use against plate armour, the hammer face could deliver a concussive crippling blow whereas the spike could possibly penetrate the armour itself. This example is very solid and heavy, the head shaped and fluted in a most decorative almost Gothic manner. A very similar head is seen on the warhammer of Prince Vasily Obolensky-Turenin in the Armoury Moscow, late 16th century. The shaft of the warhammer is darkwood probably oak, carved with ribbing for its entire length, fitted with long steel side mounts attaching the head for strength and reinforcement. Hole for a lanyard. Some wear and damage, this was a utilitarian weapon used for war circa 1575.
