This strop is produced by the folks at Wood Is Good Co.® They designed this strop for the woodworker in mind but it works equally well on just about any bladed tool or knife. The synthetic material is relatively hard so it can support the blade and produce a perfect edge. This strop was designed to work with the aluminum oxide powder. Once you sprinkle the powder on the strop you’re ready to take your sharpening to the next level. The workable area on this strop measures 6 3/4" x 1 1/4". Since it is small it is best used on carving and other small cutting tools. The edges of the strop feature a rounded edge and a 45 degree edge for honing carving tools.
