Had a question about how I de-hair rawhide. After the hide has been dried on a stretcher I will lay the hide on a flat hard surface and rub screened ashes from my wood stove into the hair. I then take a hard wood stick (i.e. shovel/broom handle) and trim the end with a saw so it has a sharp edge. This is repeated as the stick dulls. Then just begin scraping against the grain of the hair until all the hair is removed. just takes a little elbow grease but makes excellent rawhide. This technique was shown to me by Pablo Lozano and Armando Deferrari from Argentina.
