Sai Daggers made of black polypropylene.  Polypropylene is near unbreakable making it perfect for making training weapons.  Polypropylene Sais are much stronger, more durable, and safer to use than steel Sais.  

These polypropylene Sai are lightweight, yet sturdy enough to cope with light and semi-contact sword sparring.  The polypropylene material is very stiff and is resistant to cuts, scrapes and nicks.

These black polypropylene Sai are perfect for practising Kobudo.  In a crowded dojo having these instead of a metal, pair can increase safety.  They are also perfect as the first pair for young children.  They can learn their katas in safety with these polypropylene Sai first, before moving on to the metal ones.

These Sai are sold as pairs.  They have a total length of 19.5 inches

• VIRTUALLY UNBREAKABLE: Polypropylene is a virtually unbreakable material. It is less prone to chips and scratches than metal and wood, and extremely hard to shatter. This makes it ideal for making training weapons used to practice Kobudo, Karate or other martial arts.
• SAFETY: The points are blunt and the edges are less sharp than traditional metal Sai. These polypropylene Sai are ideal for children, beginners, or people who train in crowded dojos.
• DESIGN: The design of the Sai follows the traditional shape used in the practice of Kobudo. The Sai is well balanced making flicks and blocks easy to perform. The overall length of 19.5 inches (49.53 cm) will suit most practitioners.
• PRACTICE: With these polypropylene Sai you can practice anywhere even crowded dojos. These practice Sai are can be taken with you for practice sessions.
• SPARRING AND SELF-DEFENCE: These practice Sai are strong enough to be used for medium to light contact sparring. This makes it easier and safer to practice your self-defence, pairs or weapon sparring.
