Large Skew Shaft – Heavy Duty Tip Only. Similar to the 15L. This is the style of shaft-making tip preferred by Bob Guge. We offer two sizes (large and small) in either left or right-handed versions. For most users we recommend the HD pens and tips as they will withstand more sideways pressure without bending.
Will only work with the Binding-Post Interchangeable-tip Pen #BPH.
Available as: Standard pen, standard tip, heavy duty pen and heavy duty tip.
