Its most likely dust, dirt or debris in the air, it gets caught under your hand, without you realizing it, and as your using the knob, you scratch it.. The dust will actually cause it..
Ever wonder how your CDs get scratched inside your CD player, its the dust that gets inside the radio, and it gets on the rollers that slide your cd player into place.. causing hair line scratches. Its true. I learned about it when I worked at Best Buy.
