List Notes:   If the item is common and a lot of people sell it I'll list a directory (froogle.com for example) that you can search for butterfly swords on and find it.  Just look at the picture to match the swords up.  Pure Wing Chun - means whether they are Wing Chun Butterfly Swords, or just generic Kung-Fu Butterfly Swords (Southern Shaolin Swords).  I put what the advertisers say, whether I agree or not in some cases.  Custom means a) are they custom made or machine made and/or b) can you give them custom specs (such as length of your arm) and have them made to fit.
