Cross Hatch Adhesion Tester Kit with Rotating 3-Blade Head & Test Result Chart - Precision Tool for Paint, Coating, Plating, Spray Finish Surfaces

I like this product, it is well made and the cutting blades are good quality. The only thing I don't like so much is when you pull the tool across a test surface with something above moderate force (because you are trying to cut into the substrate) the cutting wheel will rotate. It rotates because the only thing holding the cutting wheel in position is a small ball bearing with diameter of about 3mm. What I did as a workaround was I stuffed some rubber pieces into the gaps between the cutting wheel and the handle housing so there is less propensity to rotate out of position.
