Mason's Chalk Pencil AWTools AW29601, green, 4H, for stone and brick, pack of 10

Mason's chalk pencil AWTools AW29601 is a pack of 10 green, 4H hardness marking pencils designed for making precise, long-lasting lines on porous masonry surfaces such as stone and brick. The hard core produces fine, consistent marks that remain visible during layout, cutting and joint work. The compact pencil shape fits standard carpenter's sharpeners and is easy to handle on horizontal and vertical surfaces.

Advantages

The 4H hardness core resists crumbling and provides thin, accurate lines that are useful for detailed masonry layout. The green pigment offers clear contrast on typical stone and brick tones, improving mark visibility without excessive smudging. Supplied in a pack of 10, the pencils ensure continuity on longer jobs and reduce the need for frequent replacements.

Suitable for

• Marking cut lines on bricks and natural stone
• Layout and joint alignment in masonry work
• Transfer of measurements on porous construction materials
• DIY renovation projects involving block, brick or stone

How to use

Select a pencil and sharpen it with an appropriate hard pencil or carpenter sharpener to produce a fine point. Hold the pencil at a comfortable angle and draw along the intended line with steady pressure; the hard 4H core will create a thin, precise mark suitable for guiding cutting or aligning joints. For vertical surfaces, support the workpiece or use a straightedge to ensure accuracy. Replace pencils from the pack as needed to maintain sharpness and consistency.

Usage recommendations

Store pencils in a dry place to prevent the wood casing from swelling and to preserve core integrity. For deeper contrast on darker stone, make multiple light passes rather than pressing hard; this reduces the risk of breakage. Dispose of used pencil shavings and small core fragments appropriately.
