The 37C HD Slant is designed for the more experienced wet shaver. The slanted shaving head is not a flaw but by design to act as a guillotine, slicing the whiskers from the face rather than simply cutting. The slanted head exposes more of the blade on one side, which is most similar to shaving with a straight blade. Suitable for heavy beards, this may indeed be the last razor you'll ever need to buy.
