I would be suspect. “The white compound is aluminum oxide based, with a grade of 9000 grit. The green paste is chromium oxide based, and is rated at .5 micron, which is the equivalent of approximately 50,000 grit.”

“Chromium Oxide based” If it were pure Chrome Oxide they would say so. And they market it as knife polishing compound. Most polishing compounds contain Aluminum Oxide to cut quicker.

You can buy pure Chrome Oxide from Kremers Pigments No #44200.12100.136 $10, for 100 grams. About 3.5 oz. more than you will ever need.

I made strops from Pellon a fabric backing material, and from Sail Cloth, a polyester canvas. You can buy both from any fabric store pelon is about $5 per yard and Sailcloth about $10. Both work with Chrome Oxide.

Pellon is like Tyvek house wrap but comes in different thickness and not as shiny, it holds paste well.] Make sure not to get the glue backed one. Comes in 36 - 45 inch width, so a yard will make a bunch of strops.

I use Pellon with CBN and Diamond. Buy the mid weight about the thickness of cardstock.
