How to choose sai:

• For Demonstration: Lighter sais are preferred for demonstration. Some martial artists choose sai with reflective materials to add flash to their performance. The aluminum sai is lightweight and the preferred choice for demonstrations. The hexagonal shape reflects more light, making a sai demonstration more impressive.
• For Strength and Speed Development: To develop muscle strength and increase speed, use a said made from a heavier material, such as chrome. This will increase strength in your arms and wrists. Then, when switching to a lighter sai for demonstrations or sparring, you will naturally move faster.
