Need to mark or score hard materials? This HARFINGTON scribe pen is a handy tool for DIYers, mechanics, or crafters. It has a super-hard tungsten carbide tip that makes crisp lines on metal, glass, tile, ceramic, wood, or even marble. The pen-style design is comfortable to hold, with a knurled grip to prevent slipping and a pocket clip for easy carrying. There's even a built-in magnet to pick up tiny metal shavings – genius! It comes with five extra replacement tips, so you're set for a long time. To use, just hold it at a 45-degree angle and draw along a straight edge to score glass or tile, then snap it cleanly. At about 5.1 inches long, it's compact but tough. Made from chrome-plated alloy steel, it resists rust and won't break easily. Whether you're engraving, etching, or just need a precise marker, this scribe pen gets the job done. A must-have for any workshop or craft table!
