Using bath/hand soaps has been mentioned on here but this is the first video I have seen on it. Dove seems to perform similarly to Ivory soap as a substitute for a dedicated shave soap from what I have seen on your video. I have tried Ivory soap in the past just to see what it would do. It is a nice trick to have up your sleeve for the times you don't have a shave soap on hand. That is a good looking scuttle and a very generous offer too.
