Determining the sharpness of a blade requires precision and consistency beyond the standard methods like cutting printer or newspaper or shaving arm hair. To truly prove sharpness, professionals and enthusiasts rely on the BESS certified PT50 Series Sharpness Tester from Edge-On-Up.

The BESS (Brubacher Edge Sharpness Scale) standard, developed by Mike Brubacher, provides an accurate measurement of knife sharpness. Adopted widely, this user-friendly test method is trusted to determine the sharpness of a blade.

The PT50 Series of Edge-On-Up Sharpness Testers give you the ability to measure and quantify the level of sharpness of any tested edge. These systems work by measuring the force in grams required to cut through a standardized and calibrated test medium. The result is a numerical output on the display that allows you to compare the relative sharpness of edges.

To provide more context, a table has been created to show how the score relates to the total BESS scale, ranging from 2000 BESS for an unsharpened knife to 0 BESS for the highest sharpness achievable. Knives with a score below 50 BESS are considered razor sharp. Lower BESS values indicate sharper blades, as less weight is required for cutting.
