I've already used pointed sai and they're nothing. Second of all, I do know how to use a sai and I'm actually quite proficient with them. Third of all, I do know about sais. The reason that I asked if the Shureido was solid is because I've run into a few brands that are hollow. Also, I never said that the blades would be sharp, they won't, they'll be rounded. The reason that I want them bladed is for the effect. While I know how to use the sai I also like the showy side of them.
