This is a flattened, narrow shape spear type pen. It is sharpened on both sides, giving you twice the amount of burning time before re-sharpening. It is versatile in flat burning as a great line pen and a pen that can make graceful gossamer curves.

Replaceable Tip Burning Pens

New! Replaceable Tip Handpiece, Version 2.0!

Replaceable Tip Handpiece, v 1.0

This is Detail Master replaceable tip handpiece (v 1.0). It has a jackplug at the other end of the cord for conveniently plugging into the Detail Master burning system control box. Included with the handpiece is a Slip Lock for locking the tip into the handpiece. Please note that the slip lock gets hot with use; it is suggested that you purchase additional Slip Locks so you do not have to change them from one tip to another. The Slip Lock spreads the pen tip's prongs, making a better contact.
