Scale Pen #25 – 3mm Regular Curve
Lateral Line – 3mm (0.1181″ – approximately 7/64″) Regular Curve – Fixed Tip Pen.
Used much like the #21, the #25 has a specialy formed tunnel that leaves a raised rib in the center. When scales are burned in rows, a raised lateral line is left.
Heavy duty cord is recommended for all scale tips. Our brass brush is perfect for cleaning these tips.
