A pike was a type of hand-held melee weapon. This weapon was a long thrusting spear with a shaft supporting a spearhead.
On Rigel VII, this was one of the weapons available to a Kalar warrior. The spearhead was shaped like a clover leaf. The connection between spearhead and shaft had feathers attached to it. Some of these weapons were decorated with a banner.
During his skirmish with one of these warriors in 2254, in an illusion created by the Talosians, Captain Christopher Pike chose a mace over this weapon, before selecting the weapon as the reached the top to the stairs, poking it into the Kalar's chest. (TOS: "The Cage", "The Menagerie, Part II")
