The general consensus we've come to is that if a product doesn't have a name, we just pretty much call it what it is (i.e. gun, sword, head, etc.).
As for where we draw the line, well it's safe to say that if it's a KO (copy of an existing product) we do not add them. They have to be "original" products from said company. It's pretty safe to say that if it's sold at BBTS we can add it, since AFAIK they have a no KO rule.
Hope that answers your question Hellscream333, if not I'll let Engledogg or Shmax add their 2 cents.
