Opinions of ceramics

[tuhkis]

Does ceramic blades do the job as a pocket knife in an office?
Cutting rope, opening letters etc.
Nothing harder...
How about resharpening?

 

[Cliff Stamp]

Ceramic blades tend to be fairly thick compared to high end steel blades as ceramics are brittle and need a decent cross section to avoid fracture. So while they will handle low stress cutting, a decent steel blade will easily outcut them by a large margin. As for sharpening, it is possible with a diamond or SiC stone.
