If you have been shaving with cartridge razors your entire life, picking up a safety razor for the first time can feel like stepping into a different world. A better world. The double edge razor has been around for over a century, and there is a reason it never disappeared — it simply works better than anything the big brands have come up with since.
This guide covers everything you need to know to get started with single blade shaving razor technique, from choosing your first razor to building a lather that actually protects your skin.
What Is a Safety Razor?
A safety razor is a shaving instrument that holds a single, double-edged blade between a protective head and a handle. Unlike a straight razor, the head geometry limits how much blade is exposed to your skin — hence the name. Unlike a cartridge razor, you are working with one sharp blade instead of three to five dull ones dragging across your face.
The DE safety razor (double edge) is the most common type. The blade is cheap, universally available, and replaceable after a handful of shaves. You get a closer shave with less irritation, and you stop paying four dollars per cartridge refill.
Why Switch from Cartridge Razors?
- Less irritation. One blade passing over skin causes far less friction than multiple blades. If you deal with razor burn, ingrown hairs, or bumps, a single blade shaving razor can change everything.
- Closer shave. A sharp double edge blade cuts hair cleanly at the surface rather than the lift-and-cut mechanism of cartridges, which often cuts below the skin line and causes ingrowns.
- Lower long-term cost. A quality razor lasts decades. Blades cost roughly ten cents each. Do the math against your current cartridge spend.
- Less waste. A single steel blade is recyclable. A plastic cartridge with embedded strips, lubricant pads, and multiple blades is not.
Types of Safety Razors
Closed Comb vs. Open Comb
A closed comb (also called a safety bar) razor has a solid bar beneath the blade that provides a layer of protection between the edge and your skin. This is the standard recommendation for a safety razor for beginners — it is forgiving and predictable.
An open comb razor has teeth instead of a solid bar, allowing more blade exposure and better lather flow. Open combs handle longer stubble well and tend to shave more efficiently, but they require more respect for blade angle.
Mild vs. Aggressive
Blade gap and exposure determine how aggressive a double edge razor feels. A mild razor keeps the blade closer to the guard, producing a gentler shave. An aggressive razor exposes more blade, removing more hair per pass but demanding better technique. Beginners should start mild and work up.
Adjustable Razors
Some razors let you dial the blade gap from mild to aggressive. These are excellent if you want one razor that can handle a light daily shave and a heavy three-day growth equally well. They tend to cost more upfront but offer real versatility.
How to Choose Your First Safety Razor
- Start with a closed comb, mild-to-medium aggression razor. This gives you room to learn technique without punishing mistakes.
- Pick a handle length that suits your grip. Longer handles offer more control for those with larger hands. Shorter handles are more maneuverable around the jawline and under the nose.
- Choose a three-piece or two-piece design. Three-piece razors (cap, baseplate, handle) are the simplest mechanically and easiest to clean. Butterfly-open designs are convenient but have more moving parts.
- Budget matters less than you think. A well-made razor in the thirty to fifty dollar range will last you years and shave beautifully.
Blade Selection Basics
Here is the part that surprises most beginners: the blade matters as much as the razor. Double edge blades vary significantly in sharpness, smoothness, and longevity. A blade that works perfectly in one razor may feel rough in another.
Buy a sampler pack with five to ten different brands. Try each blade for three shaves before judging it. Keep notes. After working through the sampler, stock up on the one or two blades that felt best in your specific razor. This process takes a few weeks but saves years of mediocre shaves.
Your Razor Is Only Half the Equation
Most guides stop at razor and blade selection. That is a mistake. The single biggest factor in shave quality — comfort, closeness, and skin health afterward — is what sits between the blade and your face. The lather.
Canned foam and gel from the drugstore are designed for cartridge razors. They are thin, dry out fast, and contain ingredients that irritate skin. When you switch to a double edge razor, you need a lather that actually does its job: cushioning the blade, keeping hair hydrated and upright, and letting the edge glide without friction.
Why Tallow-Based Shaving Soap Matters
Tallow — rendered beef fat — has been the gold standard for shaving soap for generations, and for good reason. Its fatty acid profile closely resembles human skin lipids, which means it moisturizes while you shave rather than stripping your skin dry. A proper tallow soap produces a dense, slick lather that stays wet on your face through multiple passes, exactly what a safety razor demands.
Artisan soaps built on a tallow base outperform commercial products in every measurable way: slickness, cushion, post-shave feel, and skin nourishment. The difference is immediately obvious the first time you load a brush and build lather from a quality puck.
If you are looking for a place to start, PasteurVision Shaving Soap pairs exceptionally well with a beginner setup — the tallow and konjac base generates a rich, protective lather with minimal effort. Browse our full shaving soap collection to find a scent profile that suits you.
Do Not Skip the Post-Shave
A safety razor shave opens your pores and removes a thin layer of skin along with the hair. What you apply immediately after matters. An aftershave balm or splash closes pores, soothes irritation, and restores moisture. Skip this step and you undo much of the benefit of upgrading your shave. Our post-shave collection is formulated specifically to complement a proper wet shave — no alcohol burn, no synthetic fragrance, just ingredients that help your skin recover.
Putting It All Together
The path to a great shave is simpler than the marketing from big razor companies wants you to believe. A quality safety razor for beginners, a blade that matches it, a tallow-based shaving soap, and a good post-shave product. Four things. That is it. You will spend less money, produce less waste, and walk away from the mirror with better skin than any five-blade cartridge ever gave you.
Start with the razor. Dial in your blade. Then invest in lather and post-shave — because that is where the real difference lives.
