Alka spear is made of wood.
It is 290 to 300 centimetres long, with a diameter of 32,9 mm. At its top is an iron point 30 cm long. Just below half the length of the spear is the apple, a fixed wooden ring which protects the hand from being hit by the alka. At the bottom of the spear there is a butt, a space filled with lead to keep the spear’s balance when spearing the alka. The spear is grey in colour.
