Product Information
Full details
The Rexel Blackedge Carpenters Pencil is an essential tool for carpenters, joiners, and builders who require precise and durable marking on rough surfaces. Its 5-ply rectangular design provides a reliable grip and prevents the pencil from rolling off uneven workbenches, though the unique flat shape requires a specialized sharpener or a steady hand with a knife to maintain the ideal point.

FAQs
Can these pencils be used on metal surfaces?
While they are optimized for wood and masonry, they can mark clean metal, though the graphite may wear down faster.
Are these pencils refillable?
No, these are traditional wood-cased pencils meant to be sharpened until the core is depleted.
What does the red barrel signify?
The red barrel indicates that these specific pencils are the medium lead grade.
How do I sharpen these without a dedicated sharpener?
Use a standard utility knife to carefully carve back the wood casing at an angle until the graphite is exposed.
Are they water-resistant?
The graphite marks are generally water-resistant once applied to rough surfaces, though they can be smudged or washed away with heavy solvent.
Troubleshooting
Lead keeps breaking during sharpening
Use a sharper blade and apply less pressure, shaving the wood away in thinner layers.
Markings are too faint on the surface
Ensure you are using the correct grade for the surface material and press slightly harder to deposit more graphite.

Setup, Compatibility & Care
Because the Rexel Blackedge features a non-standard 5-ply shape, it is not compatible with mechanical or standard handheld pencil sharpeners. To sharpen, use a sharp utility knife or box cutter to shave the wood casing at a shallow angle, exposing approximately 5-10mm of the graphite strip. Store these pencils in a cool, dry place to prevent the wooden casing from warping or the graphite core from becoming brittle. To keep your workstation organized, store the pencils by grade in their original packaging to ensure you always reach for the right lead hardness.
