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 billmen.
The horseman's pick was often used as a means to penetrate thick plate armour or mail which the standard sword could not.
The injury caused by the weapon was also small and rarely immediately fatal.
Additionally, if swung too hard, the weapon often became embedded in the victim or their armour, making retrieval difficult.
