The Tamiya 74162 Fine Engraving Blade helps modellers add subtle surface detail to scale RC builds. The tungsten carbide tip gives steady, precise cuts that are well suited to panel lines and bespoke etching.
Work with the blade at about a 45 to 60 degree angle and pull it lightly along the intended line. Use several light passes instead of a heavy cut to keep grooves clean and prevent slips that could mar the finish.
