Shapton 30k 3/2/1 finish

After watching this excellent video from gssixgun YouTube - ‪gssixgun shapton part 3.wmv‬‏
(it is in 3 parts, this is part 3) I tried his recommended 3/2/1 Shapton 30k finish on A Fili Barbas Duras that I had honed all the way up on Shaptons. All I can say with the result is WOW and if you have a Shapton 30k it is worth watching this video.

I didn't quite catch it, was this razor finished with a double-bevel or was it honed all the way with tape?
