This classic design features two sharp edges on opposite sides of the blade. Preferred for its efficiency, it allows for shaving in both directions.

The most common design  of safety razor is the “3-piece”.  The top of the razor (where the blade goes) is called the head, which breaks into two parts called the cap and baseplate.  Then there's the handle.  

Other common designs include:

• 3-Piece Safety Razor : as mentioned above, this razor has 3 parts including the cap, baseplate, and handle.
• 2-Piece Safety Razor: in this type of razor, the baseplate and handle are usually a single piece, and the top cap is separate.
• 1-Piece and Butterfly Razor: as you can imagine these razors come in a single piece.  Butterfly razors usually have a twisting handle that will open the top cap to allow you to place the blade.  Several single edge razors are “injector type” where you push the blade into the head using a tool that comes with the blades.

These razors have a single blade edge and are known for their precision. They're often easier to handle and can be a better option for those with sensitive skin or finer facial hair.  Many are “injector” style meaning they have blades that come with a special tool that helps you switch out the blades without risk of touching the sharp edge.

Originating from the early 20th century, single-edge razors have evolved, but their core principle remains the same - a single sharp blade secured in a sturdy handle. The design simplicity reduces blade clogging and makes them easier to clean.

These razors stand out for their cost-effectiveness and eco-friendly nature, as they require fewer blade replacements. The single blade cuts closer to the skin, reducing the likelihood of ingrown hairs and razor bumps, common issues with multi-blade razors.

Some single blade setups utilize a longer blade providing more coverage for an efficient shave.

Adjustable safety razors are a boon for beginners, offering a customizable shaving experience. The ability to adjust the blade gap means users can control the razor's aggressiveness, accommodating various skin types and beard densities.

For newcomers to wet shaving, this adjustability is invaluable. Start with a mild setting to minimize cuts and skin irritation, then gradually increase aggressiveness as your technique improves. This flexibility allows for a personalized shaving journey, adapting to your unique needs as they evolve.

Beyond customization, these razors are also economical and sustainable. A durable, long-lasting option, they reduce waste and ongoing costs compared to disposable razors. Their versatility suits different shaving needs, from daily maintenance to managing heavier beard growth.

In essence, adjustable safety razors blend adaptability, economy, and user-friendliness, making them a top choice for beginners in wet shaving.

Closed comb and open comb safety razors are two different designs, each with its unique characteristics and use-cases. Understanding their differences is essential for choosing a razor that best suits your shaving needs and preferences.

Closed Comb Safety Razors:

Design: Closed comb razors feature a straight safety bar with a smooth or slightly ridged surface. This bar is located directly under the blade and runs parallel to it.

Shaving Experience: They provide a gentler shave, making them well-suited for beginners or those with sensitive skin. The safety bar protects the skin by flattening it before the blade cuts the hair, reducing the risk of nicks and cuts.
 

Use-Cases: Closed comb razors are ideal for those who shave daily or have fine to medium facial hair. They are also a good choice for anyone new to safety razor shaving, offering a more forgiving and comfortable experience.
 

Open Comb Safety Razors:

Design: Open comb razors have a tooth-like structure on the safety bar. This design creates channels that guide hair and shaving cream towards the blade.
 

Shaving Experience: This type is more aggressive than closed comb razors. The open comb design allows for a closer shave and can handle longer, thicker facial hair more effectively.
 

Use-Cases: Open comb razors are preferred by experienced wet shavers, especially those with coarse or dense facial hair. They are also beneficial for those who do not shave daily, as they can tackle longer stubble without clogging easily.
 

In summary, closed comb razors are generally recommended for their gentleness and suitability for everyday use, particularly for those with sensitive skin or lighter facial hair. Open comb razors, on the other hand, are more suited for experienced shavers who need to manage thicker or longer facial hair, providing a closer shave but with a slightly increased risk of irritation. Choosing between the two largely depends on your skin type, beard density, shaving frequency, and experience with safety razors.

Comparing straight bar and slant safety razors involves looking at their design differences and how these impact the shaving experience.

Straight Bar Safety Razors:

Design: Straight bar razors, often synonymous with closed comb razors, feature a straight safety bar below the blade. This bar is parallel to the edge of the blade and provides a uniform blade exposure across the entire length.
 

Shaving Experience: They offer a consistent and straightforward shave, making them ideal for beginners or those with sensitive skin. The straight bar design ensures a more uniform and gentle contact with the skin, reducing the risk of cuts and providing a comfortable shave.
 

Use-Cases: Straight bar razors are well-suited for daily shavers and those with fine to medium facial hair. They are also recommended for people new to safety razor shaving, as they offer a more forgiving experience compared to other types.
 

Slant Safety Razors:

Design: Slant razors have a twisted or slanted blade exposure. This unique design creates an angled blade edge relative to the skin, similar to the action of a guillotine.
 

Shaving Experience: The slant design offers a more aggressive shave. The angled blade cuts hair more efficiently and with less pressure, which can result in a closer shave with fewer passes. However, this also means there's a higher learning curve and increased risk of irritation or nicks for inexperienced users.
 

Use-Cases: Slant razors are preferred by more experienced wet shavers or those with thicker, coarser facial hair. They are particularly effective for people who don't shave every day or for cutting through heavy stubble. While they can offer a superior shave for the right user, they require a steady hand and good technique.
 

In essence, straight bar razors are great all-rounders, offering a smooth and forgiving shave for a wide range of users. Slant razors, with their more aggressive cut, cater to those with specific shaving needs, like dealing with tough beard hair or seeking an extremely close shave. The choice between the two depends on your skill level, beard type, and personal preference for shaving comfort versus closeness.

Aluminum as a material for safety razors offers a distinct set of characteristics, influencing both the performance and experience of shaving. Understanding these attributes can help in deciding if an aluminum safety razor is the right choice for your shaving needs.
