Result: Chemical engineers today are not smarter than chemical engineers of the 1970s. Conventional Edge gel, essentially unchanged since its 1970 introduction (patented by S.C. Johnson), seems to work better. With Cremo, using both Dorco and Schick blades (the latest test; I think Schick may actually be sharper, but Dorco works better because it is easier to feel the blades working), it became necessary to re-shave various spots. With Edge, if the gel/foam has been wiped away with the razor then the stubble is gone as well.
Some of this might be user error in applying more Cremo than necessary.
- New Yorker article with some shaving history: “Ever since the Wilkinson Sword company started mass-producing stainless-steel blades, in 1961, every man with whiskers to cut has had no trouble cutting off his whiskers without cutting himself.” (i.e., the last significant innovations in shaving were accomplished nearly 60 years by engineers in England and 50 years ago in the U.S. by S.C. Johnson)
