tonfa or tuifa (handle) was originally a wooden handle filled into a hole on the side of a mill stone used by the okinawans for milling grain. this handle, which was easily disengaged from the mill stone, became a very effective weapon of defense. the main part of the tonfa or millstone handle, consist of a large hardwood body about 15 to 20 inches in length and a smaller cylindrical grip secured at a right angle to the main body about six inches from one end. this farm implement also used for pounding rice and digging potatoes. the techniques of the tonfa were: striking, thrusting, poking, slashing, arm bars, pinching, figure eight, vertical and horizontal spinning.

The Bo is a six foot staff, sometimes tapered at either end. It was perhaps developed from the farming tool called a “tenbin”: a stick placed across the shoulders with baskets or sacks hanging from either end. The Bo was also possibly used as a handle to rake or shovel. The Bo, along with shorter variations could also have been developed from walking sticks used by travellers, especially monks. The Bo is considered to be the king of the Okinawan weapons, as all others exploit its weaknesses in fighting it, whereas when it is fighting them it is using its strengths against them. The Bo is the earliest of all Okinawan Weapons and is made from red or white oak.

The Sai is sometimes mistakenly believed to be a variation on a tool used to create furrows in the ground however this is highly unlikely as metal on Okinawa was in short supply at this time & a stick would have served this purpose more satisfactorily for a poor commoner. The Sai appears similar to a short sword but it is not bladed & the end is traditionally blunt. The weapon is metal & of the truncheon class with its length dependent upon the forearm of the user. The two shorter prongs on either side of the main shaft are used for trapping other weapons such as Sword or the Bo. Sai was thought to be given to those in Okinawan society that the Japenese could trust to maintain order. Sai are traditionally carried in threes, two are used in combat & the third is used as either a precursor to the actual fight, & is thrown at the enemy, or as a spare in the event that one is knocked from the hand. There are many variations on the Sai with varying prongs for trapping & blocking. Sai were also used as handcuffs & were a symbol of authority in Okinawa
