Demonstrating the Edge-On-Up Edge Sharpness Tester

The Edge-On-Up Edge Sharpness Tester is a great way to quantify the results of your sharpening. This handy machine provides a precise and standardized way to test the sharpness of your edge. This short video demonstration shows how easy it is to use. You no longer have to test sharpness by cutting paper or shaving the hair on the back of your hand. It does a lot more than just saving your arm hair, it will tell you exactly how sharp of an edge you have. The old methods will tell you if your edge is sharp or dull, this tester tells you exactly how sharp or dull 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. We like to use this when evaluating products and sharpening techniques.
