I really didn't need a new linnen type strop but I saw this material (In Clark Rubber for the Aussies) for $4 per meter and couldnt help giving it a try. The whole thing including the D-rings cost around 10 bucks and has a stropping area around 18" x 2". I chalked up one side with white sidewalk chalk and I really like it.
I've only used it twice and the razors were in pretty good shape so its hard to tell, but i think the chalked side actually made a little improvement to the smoothness of the shave. Could be my imagination though, but I'm really happy with it.
