I'm just getting into the hobby and I got a new Heirloom 4 Sided Vintage Style Paddle Strop which I purchased from an online seller. It is labeled .5, 1, 3, and then what seems to be brown leather on the fourth side. It did not come with instructions. Also, the three sides with numbers seem to have a white and brown powder infused into them. I am assuming that .5, 1, 3 are for the micron notation and the brown leather is for simple stropping?

So my questions

1. Are the .5, 1, 3 sides infused with paste?
2. If so, is the .5 cosidered coarse, 1 medium and 3 fine?
3. Do the infused sides need to be re-surfaced with paste every so often?

Also does anyone have instructions?

I think this strop is beautiful and I'm sure I'll be doing business with Tony in the future. Thanks in advance.
