Our engineers develop the following machines for testing razor blades:
Razor Edge Durability & Sharpness Tester
A specially developed machine utilising cutting force measurement that gives accurate and realistic sharpness and life determinations for both quality control and R&D purposes. Fully programmable automatic machine. Click here for more
Razor Edge Sharpness Tester
Using the same principle as the above machine, this unit can quickly assess the cutting performance sharpness only of all types of razor blades. Click here for more
Razor Safety System Tester
A unique device designed to objectively compare the risk of cuts and abrasions to the skin of different razors and shaving systems.
Electric Razor Durability Tester
Utilising synthetic hair this device enables the longevity and performance of a electric shaver to be accurately monitored and compared, suitable for quality control and R&D.
Razor Instrumentation System
A bespoke system for monitoring the performance of razors during actual shaving. Options are available to measure the number of strokes, shaving forces, vibration, noise and skin contact time.
Razor Blade Edge Position & Protrusion Measuring Instrument
A non-contacting laser powered position measurement system for accurate determination of blade position and edge protrusion within a cartridge or moulded assembly.
Mechanical Wet or Dry Shaving Test System
Based on a CATRA invented simulated facial surface (SIMFAC) with hair and follicular depressions, we have developed a device to objectively measure the closeness, forces, vibration, noise and to photographically examine both statically and dynamically the shaving process and resultant shave surface.
Laser Goniometers – Our bespoke devices that measures sharpened edge geometry and tip condition of many different knives and blades, from hunting knives to large industrial cutters. Various models available. Click here for CATRA Goniometers
