That resembles the mentioned suede 3rd piece on a Kanayama strop. The primary stopping surface on quality strops like Kanayama are indeed smooth to the point of shiny. They require no creams, conditioners, oils. They need only a rub with the palm of your hand. If expense is a worry consider that a cheaper Kanayama is around $120.00, you pay lots for collections of stones, jnats, and razors, and all those stones and the like aren't worth a cent if you have a poor strop.
