6 Best Adjustable Safety Razors: Fine Tune Your Shave

Adjustable safety razors are a unique subset of the safety razor.  With a few simple adjustments, you can drastically alter the shaving experience.

Whether you want a shave that delivers ‘baby butt smooth’ results or one that leaves behind a bit of grit – the adjustable safety razor provides control like no other razor available.  

Today we’ll be reviewing some of the best adjustable safety razors currently available, including the popular Merkur Progress to the modern Parker Adjustable Injector Razor.

Let’s begin.


Here is a comparison of the key features between each of the adjustable safety razors we reviewed:

1. Merkur Progress

Adjustment Settings: Continuous 1-6 | Razor Blade Type: Safety Razor | Country of Origin: Germany | Weight: 3.17oz | Length: 3.47″

The Merkur Progress adjustable safety razor is popular due to its reliably consistent results.  With a continuous adjustment knob, you can fine-tune the blade exposure to your preference.  One significant difference between the Merkur Progress and the Futur is the aggressiveness at its mildest setting.  This mild aggression makes the Merkur Progress a beginner-friendly adjustable safety razor yet offers enough aggression for the wet shaving expert.  

For construction, the plastic adjustment knob coupled with polished chrome plating to the handle and razor head provides a dash of elegance to the bathroom countertop.  Lastly, Merkur does make a long handle variety, perfect for men with larger hands.

2. Rockwell Razors 6C

Adjustment Settings: 6 | Razor Blade Type: Safety Razor | Country of Origin: China | Weight: 3.53oz | Length: 3.74″

Founded in 2014 as part of a successful Kickstarter campaign, Rockwell Razors does things a little differently regarding adjustable safety razors.  Rather than relying on a turn-knob on the handle, the Rockwell 6C includes three metal plates that offers six different blade gaps.  

With this unique adjustable design, the Rockwell 6C has its fair set of advantages and disadvantages.  The advantage is that it contains no moving parts, so nothing can get jammed or worn out.  Additionally, with the Rockwell 6C, you don’t need to worry about using any of the other plates once you find your preferred level of aggressiveness.  

However, there are a few downsides you should know. First, if you like to use two levels of aggressiveness while shaving, it’s pretty laborious to switch out the plates mid-shave (unscrew the cap and handle, lift the blade, swap the mount).  Secondly, if you only require one level of aggressiveness, the two other included plates provide no actual use.  

Ultimately, this is a unique take on the adjustable safety razor.  The craftsmanship is in line with the price range as it contains a zinc-alloy body with a chrome plating finish.  Lastly, the knurled grip provides a bit more security while shaving.

3. Merkur Futur

Adjustment Settings: Continuous 1-6 | Razor Blade Type: Safety Razor | Country of Origin: Germany | Weight: 4.44oz | Length: 4.30″

The Merkur Futur adjustable safety razor is perfect for experienced wet shavers looking for an intensely aggressive shave.  While the razor has six adjustment settings, the Futur is still quite aggressive even when set to one. 

The Futur is both long and heavy. For length, the Futur is 4.30″, the Merkur Progress is only 3.47″. In addition, the Futur weighs in at 4.44oz; the Merkur Progress is only 3.17oz. Lastly, the head on the razor is a fair bit larger, which may result in it being tough to navigate tight contours, especially around the upper lip.

For the design, the Futur is among the most beautiful safety razors available.  The minimalist and high-quality design of this razor is available in a chrome or brushed chrome finish.  

4. Feather Adjustable Double Edge Shaving Razor

Adjustment Settings: 2 | Razor Blade Type: Safety Razor | Country of Origin: Japan | Weight: 1.2oz | Length: 4.05″

Widely revered for their award-winning safety razor blades, Feather also makes an equally impressive adjustable double edge safety razor.  This adjustable razor has two blade gap settings that’ll make the shave either mild or aggressive. There is no ability to fine-tune the aggressiveness like other safety razors we reviewed. However, despite the lack of adjustment settings, both the mild and aggressive settings should suffice for most users.

When using this razor, expect the large ribbed ergonomic grip to provide greater control, allowing more precise passes.

Lastly, when it comes time to refresh the blades, the butterfly safety razor design makes swapping the razor blade with a new one relatively easy.

5. Parker Variant

Adjustment Settings: Continuous 1-5 | Razor Blade Type: Safety Razor | Country of Origin: India | Weight:  4.0oz | Length: 4.0″

The Parker Variant adjustable safety razor is a fan favorite commonly mentioned on forums such as Badger & Blade and shaving websites like Sharpologist.  The Parker Variant does everything right when it comes to adjustability and performance.  The continuous adjustment knob found on this safety razor allows just about anyone to fine-tune the aggressiveness to their preference.  

The knurled handle and adjustment knob gives it an engineered appearance while also providing a confident grip even if your hands are coated with a slick shave cream.  Lastly, the composition of this razor is a brass frame that has been treated with a satin chrome finish.  It’s a good and affordable adjustable safety razor.

6. Parker Adjustable Injector Razor

Adjustment Settings: 5 | Razor Blade Type: Injector | Country of Origin: India | Weight: 1.23oz | Length: 4.96″

The Parker Adjustable Injector Razor elegantly blends the design between a cartridge razor and a safety razor. A familiar cartridge-like handle paired with the adjustment dial of a safety razor, the Parker Adjustable Injector Razor delivers close and comfortable results.  

While the design is the most apparent difference between this razor and others on the market, the weight is also significant.  At only 1.23oz, the Parker Adjustable Injector Razor is light.  Therefore, carefully applied pressure will be necessary to cut through facial hair.  

Another critical difference between this razor and other adjustable safety razors is the type of razor blades compatible with it.  Rather than a standard safety razor blade, you’ll need to use an injector razor blade.  Only a few brands make this type of razor blade, with the most notable being Schick and Feather.  

Lastly, the Parker Adjustable Injector Razor relies on a stainless steel body, ensuring that it will never rust or corrode.
