Precision "knife edge" ski true bar for checking the flatness of a ski base. Wear and tear of skiing causes uneven wear on the base and edges creating instability. A regular inspection of flatness insures top performance for your prized skis. Hold your ski up to a light source with the True BEAST across the base and sight along the length of your ski to see if light shows through, indicating either a concave or convex base condition. Gently pull True BEAST along the entire ski length. Size: 6" (150mm)
