How to use

Place the 5.6 mm lead in position and use the clutch mechanism to advance the core as needed. Mark or sketch directly on the surface, using the engraved ruler and scale for measurements. When the tip dulls, open the integrated sharpener to restore a precise point and continue working. Because of the thick HB lead, apply moderate pressure to avoid excessive breakage.

Recommendations

For best results on very rough materials, test the pencil on a scrap piece to determine the optimal pressure and sharpening frequency. Store the pencil in a dry place to preserve the brass finish and lead condition.
