I was shaving with DE for awhile (including slants), was satisfied with the results minus some persistent neck irritation. Then, I decided to move to SR. Got a nice 6/8" DOVO Best Quality, professionally sharpen by a vendor. Tried it few times and was amazed how difficult it was to come even close to the closeness I was getting from my Slant DE. Then, I got Feather AC SS with Professional Blade and within a week I was blown away how nice it was. Great shaves, never before experienced closeness, no irritation. I'm also a head shaver so I started to use the Feather on my head as well. Same thing.... unbelievable shaves. After months of that I decided to get another SR, this time DOVO 5/8" Prima Klang also shave ready from a vendor. First shave was at best so, so. It didn't get much better later with me constantly needing to do ATG and polishing with my Feather AC. Am I forever stuck with the Feather? I really like SR and everything that comes with it but how come with my SRs I can't even get close to the sharpness and comfort of the Feather AC?
