Thread: loom strop: pre-pasted or not?

I'm looking to buy my first strop and as I don't have a good place to hang a hanging strop I decided on buying a loom strop.

The only one that's easily available to me is the Herold Solingen one, which has 3 variations; 2 clean sides or one side clean and the other pre-pasted with either green or red paste.
Here's an example of one pre-pasted with red paste: https://www.sharpeningsupplies.com/H...p-P693C11.aspx
According to the description, red has particles between 2 and 4 micron in size, green around 6 micron. This seems a bit large compared to what's normally adviced around here (0.5-1 micron).

As I don't have any stones, I was wondering if the red or green paste would work well to refresh the edge or if I'm better off buying the non-prepasted version and buying paste separately with smaller size particles?
