These look pretty sword-like to me. This is James's coil but it's identical 
to Richie's :)

I think a lot of it is in the photography technique used. Richie uses 
stills from a video camera that make the streamers look much fatter and 
brighter. If you wired up a staccato controller to one of these SSTCs and 
photographed it with Cap'n Corona's high-end digital camera (or an 
old-fashioned film camera like Steve Ward uses) then it would probably look 
pretty similar.
