This scientifically designed tester assesses knife sharpness using a certified synthetic wire. Simply apply gentle pressure to the wire with your knife. The accompanying scale records the pressure exerted until the wire is cut, providing your test result in grams on the BESS (Brubacher Edge Sharpness Scale) C-scale. A lower BESS value indicates a sharper knife, offering a concrete numerical assessment of sharpness that eliminates guesswork. Understanding the BESS Standard: The BESS standard, developed by Mike Brubacher, offers a user-friendly method for evaluating knife sharpness. Scores on the scale range from 2000 BESS for an unsharpened knife to 0 BESS for ultimate sharpness. For reference, a double-sided sharpened razor typically scores around 50 BESS. Given that the test measures only a small portion of the edge, it's recommended to assess three areas: the tip, middle, and heel. A weighted average of these values provides a comprehensive assessment of sharpness. Essential Materials: For accurate comparisons, certified test materials are necessary. Edge-On-Up provides the required materials, including the DoubleX test medium capable of conducting 325 measurements. FAQs Q. Which test methods come with the PT50A Industrial Edge Tester? A. This one comes with everything you need to use BOTH the Aluminum Test Fixture with the Test Media AND a 25 count package of the Disposable Test Clips with the Clip Base. It essentially comes with everything possible. Q. I've received my Edge On Up Tester and don't see the Test Media. What should I do? A. The Test Media is preloaded into the Aluminum Test Fixture. If you do not see a strand of media coming through one of the feed holes, slide the black rubber piece off of the bottom of the fixture. A role of Test Media should be inside. Q. I've opened my New Edge On Up Tester and found a small empty box that says "Consumables." Should this box have something in it? A. No. The box will be empty. It is included as a packaging spacer and has been labeled "Consumables" for customers to use as future storage.
