Pica 541/24 Green Stonemason Pencil is a professional marking pencil for hard, dry jobsite surfaces. This is a marking pencil designed for layout and marking on stone, concrete, wood, dry lumber, and cardboard. Model Number: 541/24. If you work around rough material that chews up ordinary pencils, this is the kind of simple, dependable tool that earns a spot in the truck.

The big reason this pencil matters is the 10H graphite lead. That hard lead is meant for dry, abrasive surfaces where softer carpenter pencils can smear, wear down too fast, or snap when you bear down. On concrete block, stone, and similar material, that gives you a more durable mark with better resistance to breakage.

Pica builds this model in its Classic Line with an oval body shape, which is the right call for masonry work. The oval profile helps keep the pencil from rolling away when you set it on uneven stock or a slab edge. It is a small detail, but on real jobsites it saves aggravation and keeps the pencil where you left it.

At 9.45 inches long, the pencil gives you enough length for a full grip even with work gloves on, while the slim 0.35 inch body stays easy to carry in a pouch or apron. The wood body is described as easy to sharpen, so you can quickly get the point shape you want for rough layout marks or more controlled line work.

This pencil is intended for most dry surfaces and the marking can be removed with a damp cloth when needed. That matters for layout work where you need visibility during the cut, fit, or install stage, but do not want permanent marks left behind once the job is done.

It also fits neatly into the wider Pica system. Source data lists compatibility with PA505/01, PA505/02, PA505/03, and PA505/04, and the product description calls it a refill for the Pica Pocket Quiver & Blade in one. If you already use Pica marking gear, this pencil is an easy match instead of a one-off purchase.

Who should buy it? Masons, concrete workers, remodelers, carpenters, and general contractors who regularly mark rough, dry building materials. Serious DIY users doing masonry, hardscape, or framing projects will also get more use out of this than a basic office or school pencil. It is a straightforward jobsite consumable, but it is the right one for the work it is meant to do.
