Quality tests on multi-blade shaving systems

Initial cutting performance tests (sharpness tests) and durability tests on razor blades by means of a patented process to measure the cutting force.

Visual inspections and microscopic analyses on razor-cartridges via a contact-free measurement of the razor blade geometry using a 3D profilometer and high-precision measuring technologies.

  How are multi-blade shaving systems tested for quality?
1. Sample determination and documentation according to a defined sampling and identification pattern
2. Visual inspections and microscopic analyses on the samples
3. Contact-free measurement of the cartridge geometry using a 3D profilometer in the micrometre range
4. Determining the razor blade’s initial cutting performance (sharpness) and durability
5. Constant improvement process
