How sharp is sharp enough? With Edge-On-Up Sharpness Testers, you no longer have to rely on guesswork. These precision instruments allow you to scientifically measure and quantify sharpness, giving you a consistent and repeatable way to compare edges.
Edge-On-Up testers use a standardized, calibrated testing medium to measure the force required to cut through it. This results in a numerical sharpness score in grams (often referred to as a BESS score), which makes it easy to track your sharpening progress over time, compare different sharpening methods and tools with objective data, as well as evaluate factory edges vs. professionally sharpened edges.
Edge-On-Up testers use BESS-certified test media, ensuring consistency and reliability across all tests. Whether you're sharpening kitchen knives, woodworking tools, or pocketknives, the BESS score provides a clear benchmark for sharpness performance.
