i've been looking for a four sided paddle strop to touch up my razors without getting a 8k or 12k stone or a barber's hone. i figured i would get one for four sides of leather then apply different pastes and CrO or FeO.

Product Description
The 4-sided paddle is 13 1/2" overall with 8 1/4" sharpening surfaces that are 1 1/4" wide on each side. Numbered for easy use, start with the coarse side-black Arkansas stone, then the #2 red polishing strop, the #3 black buffing strop on the third side follows, and finish with #4 on the fourth regular strop side with Russian leather. #4 is also a great strop for everyday use.

the material on each side seem like they would complement each other very well in bringing together a fine edge on a razor.
