The SVS-38 Short Tool Jig has two parallel flanges that guide on both sides of the universal support. The design makes this jig extremely stable, and the tool always stays perpendicular to the grinding wheel even when you turn it. The design is a great advantage, as you can concentrate on sharpening or honing at all times without having to worry about whether your tool is perpendicular. The minimum tool length is 45 mm (1.77") at a 20° sharpening angle, and the maximum width is 38 mm (1.5").
