The Sai (釵) is a distinctive Okinawan weapon, typically wielded in pairs. It resembles a trident, with two curved prongs and a central handle. Traditionally made of metal, modern training sai are often made of wood or plastic.  

The sai is a versatile weapon designed for both offensive and defensive techniques. It can be used for:  

• Stabbing: The pointed prongs are ideal for piercing attacks.  
• Striking: The handle and prongs can be used to deliver powerful strikes.  
• Parrying: The sai can be used to deflect incoming attacks.  
• Grappling: The sai can be used to control an opponent’s limbs or weapons.  

The sai’s unique design and versatility make it a formidable weapon in the hands of a skilled practitioner.
