Solid PSA Black Silicon Carbide

Used a 6-inch disc on a small knife-sharpening project, and the silicon carbide cut smoothly without loading up. The adhesive backing held tight on my sanding block the whole time. Exactly what I needed for that glass edge cleanup too.

Finally got around to using these for sharpening my kitchen knives and the 14" size covered the whole blade in one pass. The grit is consistent across the disc so there are no uneven scratches. Exactly what I needed for the final honing step on my chisels as well.

I needed a finer grit for polishing stone countertops and these discs worked perfectly—the adhesive backing held strong through the whole job. The 12-inch size covered a lot of surface area quickly. Will be ordering more when I need to polish metal.
