You might try another blade... duds do happen sometimes. It's rare, but it happens.
ok, this is weird but I have been having awesome shaves with my slant for a week or so now but yesterday I put in a new blade and had the worst shave ever. It pulled and hurt like hell! I checked to make sure blade was seated in correctly and it was. I did not do anything different with my prep. I am stumped and hope that it was a fluke.
Has anyone else had such a wide swing with their slant experiences?
