Overview

Accurately testing the sharpness of a blade requires more than just traditional methods like cutting paper or shaving hair. The BESS certified PT50 Series Sharpness Tester from Edge-On-Up provides the precision and consistency required by professionals and enthusiasts alike.

Based on the BESS (Brubacher Edge Sharpness Scale) developed by Mike Brubacher, this system offers a precise measurement of knife sharpness that is widely trusted and used within the industry.

Product Details

The PT50B Sharpness Tester from Edge-On-Up measures the force in grams required to cut through a standardized test medium, providing an exact numerical reading for blade sharpness. A score of 2000 BESS indicates an unsharpened knife, while a score of 0 BESS represents the highest level of sharpness. Knives with scores below 50 BESS are considered razor-sharp, with lower BESS values indicating sharper blades.
