Results Chart for the Edge-On-Up Edge Tester
What do the numbers on the Edge-On-Up Tester mean?
The Edge-On-Up testers are a great way, in fact the only way, to get a quantifiable result when testing the sharpness of an edge. They work by measuring the grams of force required to cut a standard test media. The fewer grams of force require to cut the media, the sharper the edge.
Of course, the number of grams required to cut the media isn't enough information on its own. It is really just a number without something to compare that number to. With that in mind, the table below has ranges that give a reference to compare results to.
