Add fine panel lines to models with the Tamiya 0.15mm tungsten-carbide engraving blade. A color marking on the shank identifies the blade size.
Includes one 25mm blade with a 2mm shank and a case that holds up to ten blades. Compatible holders include Tamiya 74139, 74050, and 74112. For controlled scoring, hold the blade at 45–60 degrees and use repeated light passes.
