Thaddru is not my teacher, we are the same rank and have the same teacher. As to his comment of how some people would say SD is similar to karate or TKD, I will let him explain what he meant.
Which weapons are you referring to exactly? I believe you will pick sais as one. I am currently trying to find the article on Kungfumagazine.com that describes the Chinese sai. It's form was similar to the modern version however along its length the blade was segmented like the tail of a scorpion. On a recent trip to China, a SD group visited Quanzhou Shaolin Temple and took this pic of one of their weapons racks. Notice what is on the rack:

Here is a pic of some excavated weapons found at the newly discovered southern Shaolin temple. Notice the weapon third from the left.
Is this sufficient for the sais or are you going to make me go through pages and pages in order to find the write up on Chinese Sais on kungfumagazine.com?
