They are made from emery, wax, and a pigment to dye them. The coarse side is 1F emery and the fine side is 4F emery if I remember correctly.
You can use them dry, with cold water, or cold lather. Hot liquid will melt the wax.
When they get too smooth, you wipe them down with a little bit of turpentine - which is also a good test to see if it is a skute.
Being emery, they are fast cutters so 4 or 5 strokes on each side should refresh the blade up to about the 20k-30k level.
Google should be able fill in the details of them that I can't remember at the moment.
