After three weeks of silence, I'm back with a topic that deserves this media pause: the development of a brand new adjustable razor, a project I've been working on for several months.
Genesis of the Project
The initial idea was simple in its formulation, but complex in its execution: to create an adjustable razor with a simple and durable mechanism. Not wanting to venture into the path of a traditional adjustable safety razor, which requires numerous parts and would tie up too many of our limited machining resources, I explored another direction.
My conviction is that adjusting the blade exposure constitutes the ideal parameter to allow everyone to find their optimal shaving level. This is the path I followed.
The Choice of AC Blades
To integrate an effective adjustment mechanism, I opted for AC blades, known for their thinness. This characteristic frees up valuable space to house the adjustment mechanism without compromising the overall ergonomics of the razor.
Beyond this technical aspect, I must admit that these blades count among my personal favorites — an additional reason that motivated this choice.
The First Attempts: Constructive Failure
My first approach was not conclusive. I had imagined a system where the user could manually adjust the position of the cap on different notched positions, thus modulating the blade exposure.
Unfortunately, even when working on the angles, this solution did not provide intuitive and reliable adjustment. It was necessary to go back to the drawing board.
The Slide Solution
In a second phase, I explored a cap translation system via a slide. This approach was not without risk: the danger of jamming (mechanical blockage) is real on this type of mechanism.
The major technical challenge lay in the clearance to be maintained — that subtle balance where too tight an adjustment prevents any movement, while too much play promotes jamming.
After several iterations and modifications, I finally assembled a first functional prototype. It still has some imperfections — occasional slight blockages during adjustment and aesthetics to refine — but the shaving performance has proven excellent.
Technical Characteristics
For this new razor, I drew inspiration from La Faulx for the shaving angles, but with a gap (space between the blade and the comb) of 1 mm.
The adjustment range extends from -0.15 mm to +0.2 mm of blade exposure. Depending on the chosen setting, the gap varies slightly, but in a subtle way. The adjustment is intuitive enough to be modified even in the middle of shaving, with a BBS (Baby Butt Smooth - perfectly smooth shave) consistently achieved.
Towards Version 2.0
Encouraged by these initial promising results, I'm planning a significant update for version 2, scheduled for the end of May. On the agenda:
- Complete redesign
- Optimized repositioning of the slide
- Significant improvement of the adjustment button
- Elimination of occasional blocking problems
In Conclusion
This project represents a new direction for the workshop, with the ambition to offer a modular razor without sacrificing the mechanical simplicity and durability that characterize our creations.
You can discover this prototype in action in the video below which demonstrates the operation of the adjustment mechanism. The photos will also allow you to appreciate the details of this first version, with its qualities and imperfections that we will correct for V2.
I'm eager to hear your impressions on this concept or any suggestion that could inform the final development phase.
