Roller cutters are ideal for cutting to size glass and carbon fabrics on the workbench.
Whether by hand or with templates, even highly drapable twill fabrics can be cut without distortion; more easily, more quickly, and more cleanly than with shears or knife blades. The black blade protection can be removed in order to prevent hooking of fibres at very low areal weight fabrics (< 1.5 oz/yd² or 50 g/m² respectively).
