The Edge-On-Up DCB10 is included with the PT50C and PT50A Sharpness testers and is used to hold DTC100 disposable test clips.
This product includes only the base and does not include test clips. Test Clips are not BESS Certified but provide a very quick and repeatable means of comparing one edge sharpness level to another. Test clips generally measure about 20% under BESS CERTIFIED standard scoring.
