The Edge-On-Up DoubleX test medium is a certified synthetic wire that shows a constant value when used on an Edge-On-Up sharpness tester. The can contains enough wire for 325 measurements.

The BESS-certified testing medium makes it possible to compare values on the basis of a given standard, even internationally. The test medium has a diameter of 0.23 mm and is made of temperature-resistant, moisture-insensitive polymer plastic.
