One I got recently, it is the large coarse Dragon rasp from StewMac.com, it is awesome. The other, narrower one I got very early in my woodworking hobby, I want to say from Lee Valley or Garrett Wade. It came as half of a pair of rasps, but I've forgotten what the advertised diff was. I don't generally distinguish between them, just pick whichever is handy.
