Our wide varieties of Waterstone Slips are used for sharpening gouges and other shaped edges. Their shapes can be easily modified by rubbing on #120 grit silicon carbide sandpaper to fit your particular needs. They are manufactured from quality materials and to the same high standards as are our Bench Stones. They will easily outperform any oil stone slip. Size of Round Edge Slips: 4˝ x 2˝ x 1/2˝ tapering to 3/16˝.
