How to use

Extend the 5.6 mm HB lead from the clutch mechanism and mark or sketch directly onto the work surface. Use the printed centimetre/inch scales and the 1:20 m or 1:50 m scales to transfer or check measurements. When the lead blunts, open the integrated sharpener to restore a clear edge and continue marking. Store the pencil in a tool pouch or pocket to keep it accessible on-site.

Recommendations

For best results on very hard or abrasive surfaces, check the lead periodically and replace if excessively worn. Avoid exposing the brass body to corrosive chemicals; wipe clean with a dry cloth after use.
