I’m a masonry contractor and I recently started using these instead of pencils, and I gotta say they seem to work well. They’re so much better than sharpening a pencil every 5 min, and the lines don’t blow off when I cut with a concrete saw. The tips do wear down rather fast when pressing down on a rough surface, but take some pressure off and they’ll last for quite s while.
