@rutlandstools: T Square Rule with Beveled Edge - 200mm The bevelled edges of this T square rule bring the graduations level with your stock, minimising parallax error, for the most accurate straight, parallel and perpendicular lines. Micro fine guide holes ensure pinpoint pencil placement, at 1mm increments from the workpiece edge. #rutlandstools #tools #carpentry #woodwork #joinery #cabinetmaking
