Top Picks:

Single blade safety razors fall into two main categories: single edge and double edge razors. Double edge razors, on their part, can be of the open comb, or the closed comb type, depending on the design of the shaving head. Open comb double edge razors are generally more aggressive than their closed comb cousins.

On the other hand, single edge razors can be gentler to your skin than both open comb and closed comb double edge razors. They have thicker and stiffer blades that look like small pieces of the traditional straight razor. SE razors are rarer and older than DE razors, but they seem to have a small but constant fan base.

Further, all double edge razors use standard blades that fit both open comb and closed comb models. By contrast, the different models SE razors use different blades: GEM, Injector, FHS/Autostrop, and Barber-style.

Finally, depending on their design, double edge razors fall into several different categories: twist-to-open, two-piece, and three piece razors.

    Merkur 23C

    This is a single blade safety razor that provides a smooth shave with minimum irritation. Being easy to control, 23C (review) is the perfect choice for those who’ve decided to switch from a cartridge to a safety razor.

    MK 23C’s four-inch-long handle with gritty cover guarantees maximum control while shaving despite the low weight of the razor (just 2.12 ounces). Small-handed users should be looking for the short-handle modification.

    When screwing or unscrewing the shaving head, you must not touch the bladed sides. When you pack up for a holiday, just invert MK 23C’s head and screw it backward. In this way, the safety bars will fully cover the blade.

    23C’s coating isn’t very solid, so the metal in the corners may chip if you accidentally drop the razor into the sink.
