From what I gathered so far, the best quality Sai's are made from Shureido and The "Energy Sai of Agena," from Weapons Connection. Does anyone have experience dealing with either of the two companies. Any Sai masters/practitioners have any preferences? I want to know what Sai is better quality. I did see Shureido's web page and they make a stainless steel Sai. Would any of you prefer one over the other? Any preference between round Sai and Octagonal Sai? Anyones help is highly appreciated. Thank You.
