Now With New Test Fixture 5 Gram Resolution 10 Measurements/Second Batteries Included A Standard Test for Sharpness How sharp is the edge? That is both the most important question a sharpener can ask, and possibly the hardest to answer. There are tests like cutting paper or shaving hair that are often used to demonstrate sharpness, and they are helpful to a point, but they lack the precision and standardization required to truly answer the question. However, a precise and standardized testing method is available. It is achieved using the PT50 Series Sharpness Testers from Edge-On-Up. Measure and Quantify The PT50 Series of Edge-On-Up Sharpness Testers give the ability to measure and quantify the level of sharpness of any given edge. They work by measuring the force in grams required to cut through a standardized, calibrated medium. The result is a number that can be used to compare the relative sharpness of edges. Industrial Precision and Quality There are three models of PT50 Sharpness Testers. The Edge-On-Up Pro Edge Tester (PT50B) Is intended for professional sharpeners, woodworkers and knife enthusiasts looking for a serious method of evaluating and comparing edges. The Edge-On-Up Pro Edge Tester Features: 10 measurements-per-second processor 5 Gram Resolution Portable Lightweight Design 3 Button Operation 2 AAA Batteries Included Test Medium Included The Pro Edge Tester includes a Knife Fulcrum and the New Aluminum Test Fixture.
