The predominant use of the spear was for throwing. But over the centuries they were adapted for the changing needs of hand to hand combat. It has been used in cultures throughout the world because it is inexpensive and easy to make and it is extremely effective. You can attack your enemy without getting too close.

-There are some very interesting variations to spears. The Tribal spear shown at the top of the page is one of these variations. It could be used as a thrown weapon but because of the bladed and hooked end it was also a very effective halbard type weapon. And the spike on the bottom end was very effective at securing the spear into the ground to hold ground against an attack, particularly mounted attacks. The spike could also be used in close combat and when the melee got very confused and vicious. Here is a link to learn more about the spear shown above (It is over six feet in length).
