In your newly posted video above I think the guy showed some files and stones. One of the stones had coloured circular spots on it like those in the picture here. Is the stone element within the coloured circular spots or outside the spots?
There are different brands/makes of diamond stones. The type shown in your posting above are made by DMT, I believe the diamond filings are embedded in the metal part.
Diamond stones come in different gradings, from coarse to fine. The colour coding identifies each different grading.
