Safety Razors

A safety razor is the tool traditional wet shaving is built around: a single replaceable blade held at a fixed angle by a metal head, with a guard that limits how much edge reaches your skin. That is the whole idea, and it is why a razor bought today can still be shaving in fifty years.

The differences between razors come down to geometry. Blade gap is the distance between the edge and the safety bar, blade exposure is how far the edge sits past the guard line, and together they determine how much beard a razor removes per pass and how much it forgives a bad angle. That is what people are describing, usually imprecisely, when they call a razor mild or aggressive. Efficiency and aggression are not the same thing: good modern geometry can clear a heavy beard without punishing mistakes.

Format matters less than most beginners expect. Three-piece razors come apart into cap, baseplate and handle and have nothing to break. Two-piece and butterfly-open designs trade a little simplicity for faster blade changes. Adjustables let you dial the gap up and down, and plate-based systems let you swap it. None of these is inherently better; they are preferences.

Our coverage here spans first razors, the honest signals that you have outgrown one, what aggression really measures, and the vintage market where a clean sixty-year-old Gillette still outshaves plenty of new metal.
