I have some very expensive, high quality water based diamond slurries that a friend gave me and I want to make some strops with them. I was thinking of using balsa wood because of its ability to soak up liquid. One draw back I thought of is, once it dries the diamonds will just flake off. I am just not sure I can get the diamonds inbedded enough to prevent the flaking. If anyone has a suggestion I would love to hear it. I hate to let these products go unused. This is a project I want to try for just for the sake of trying.
