I'm weird, but the nicest part of sapphire for me was that it meant i could keep my phone in the shop without worrying about the screen getting scratched from saw blades, chisels, or carbide marking knives i put in my pocket.
Of course, i guess i'd have the opposite problem of the phone scratching those things, but ...
- jaggederest 10y agoThat doesn't make sense, tungsten carbide is harder than sapphire. Carbide tools should scratch it no problem.
- DannyBee 10y agoIt varies. You are right that some are harder than pure sapphire, but it depends on the exact grade, etc, and depends on what you do to the sapphire. Suffice to say: I have tested saw blades i have against sapphire screened watches i have. They do not scratch. ¯\_(ツ)_/¯
