Single blade razors have a bad reputation. They give a better and closer shave every time, but have harder times navigating the curves of the chin and jawline. How could a single blade razor be made more intuitive and safe?
Grip strength controlled razor
Axle is a single blade razor whose stiffness can be controlled by how hard you grip the handle. To get a clean shave on flat skin, hold tightly, and when you want to move around a curve loosen your grip.
Instead of relying on a spring, you can feel the change in the handle when shaving, giving a more tactile experience.
