After every shave microscopical residue, like skin cells, water, and keratin is left on the blades. This can cause blades to feel dull, but the RazorPit Teneo uses friction to clean off the residue and thereby leaving you with a clean and sharp razor blade.
The RazorPit is designed for use with cartridge blades (while in the razor) as they are already aligned to the correct 30° angle, which ensures hassle free sharpening. It can still sharpen Double Edge blades BUT you must do this by hand and not while the blade is in your Safety Razor. If you attempt this then you need to be very careful.
To sharpen the blade by hand simply hold it by the middle and drag it across the RazorPit at roughly a 30° angle, as you would try to achieve when shaving with your Safety Razor. In theory this could double if not triple the amount of shaves you get per blade but please remember if the blade causes you irritation, switch it with a new blade and dispose of the old one properly.
Simply apply a bit of Shaving Soap or Shaving Cream to the RazorPit and begin saving money! This is the white version of the RazorPit Teneo, but we also supply it in the colour black.
