I was wondering if any one had any specific information regarding the Matayoshi style timbei in terms of design, manufacture, materials, sizing, etc. Most sources state that it is a round metal shield sized to the user, which is not terribly helpful. I know where to get the rattan shields, but I have been looking for years and haven't found any reputable sources for metal Matayoshi style timbei. When I was young and healthier, I had a shield made out of 1/4 inch aluminum which weighed 11 pounds, but I never trained with it due to its size and design flaws. Any information or pictures would be appreciated. Thank you for your consideration in this matter.
