Here is my new knife, and the blade is tungsten carbide : r/Machinists

CRKT 7103 Lake Signature - Razor Sharp Edge

Durable material: The glass scriber has a durable tungsten carbide tip and an aluminum body, so it can easily handle hard materials including hardened steel, stainless steel, ceramic and glass. Disposable briquetting tungsten carbide blades are more durable than others and are not easy to drop. Magnetic: The permanent magnets on this etching tool pick up small parts and recover steel filings from hard-to-reach places.
