Seen around the 10th thru 13th Centuries, The Norse ''Krokspjot'' Spear was similar to both the Ancient Greek Boar and Serbian Borata Spears. Regulated to Elite classes of Warriors, this was due to the time involved in both forging and above all sharpening The Spear Head. Unique for a Viking weapon, The Krokspjot featured a 3 pronged Head. The central Blade was a traditional Spear Head that was doubled edged and somewhat broader at 3 to 4-inches in width. This blade measured 5 to 8-inches. The side crescent blades were normally only sharpened on the outside of the blade cut.
The central blade was flanked by twin blades (crescent in design). The goal was to create three wounds instead of one, thus increasing the chances of a fatal strike. The Head was mounted on a wooden Pole between 4 and 6 feet. Most examples that survived are degraded with much of what is known based on reconstructive speculation.
