Edge-On-Up Home Edge Tester

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. Designed for the Home User There are three models of PT50 Sharpness Testers. The Edge-On-Up Home Edge Tester (PT50C) Is intended for the home user or hobbyist looking for a reliable way to distinguish between a well sharpened edge and a poorly sharpened one, and everything in between.
