The sai is a long, unsharpened blade with two, unsharpened projections that are attached to the handle. Because a sai can be handled a variety of different ways, it can be a lethal, or non-lethal tool. It is extremely effective in stopping sharp bladed weapons, such as swords. Traditionally sai’s were carried in three’s, two at the side and one tucked in the back, in case one sai was disarmed. Because of the versatility of this weapon, it makes for both an excellent offensive and defensive weapon.
