The horseman's pick was a weapon used by cavalry during the Middle Ages in Europe and Indo-Persia. This was a type of war hammer that had a very long spike on the reverse of the hammer head. Usually, this spike was slightly curved downwards, much like a miner's pickaxe. The term is sometimes used interchangeably with war hammer. A metal-made horseman's pick called "nadziak" was one of the main weapons of the famous Polish Winged Hussars. A weapon of late make, the horseman's pick was developed by the English and used by their heavy Billmen, a unit of heavy infantry. It was used with great success during the Hundred Years' War. A use of the horseman's pick was to tear men from their mounts.
