Replacement Tungsten Carbide Scribe for the MasterScribe by Walter Sorrells

The replacement scribe made from Tungsten carbide, is the hardest metal on earth, substantially harder than steel. As a result, the carbide scribe can expect to last stay sharp for hundreds of knives. And when it dulls, the 11 mm square carbide insert can be incremented to another corner, allowing more perfect center lines.
