Mine is a 5/8 king cutter. I gave it another shot today. I tried the hot tower after putting on a first lather, but it irritated my skin. I think I might be allergic to the west indie bay soap. I put another lather on afterwords and attempted to shave. I was able to shave both sides of my face with very little discomfort, but again I got to my chin and it started pulling no matter what angle I tried. I tried to brave through the pulling and ended up taking a small chunk out of my chin, so I gave up on the chin area and started on the neck. I couldn't get anywhere with my neck until I tried shaving upwards, then it went alright but missed lots of hairs. I eventually gave up and went to a double edge safety razor I picked up this weekend at an antique shop and a pack of cheap personna blades from walmart. My first shave with the safety razor gave me a very nice shave with one minor nick, and it felt smooth with no pulling at all. It didn't even feel like it was cutting hair, just felt like a small bar of metal was gently sliding over my wet face, yet it cut the hair so smooth. I think I jacked up my straight razor's edge by stopping due to my shakey hands, even though to the naked eye the edge looks great. Now I'm interested in a nice safety razor for SRD but I spent all my money on the straight razor set.
