What Your Opinion of This?

The secret is ceramics. This 5-1/2" long precision cutter has a ceramic point that's as sharp as an X-actly knife, stays sharp longer, is easier to maneuver in intricate cutting patterns, and is nearly impossible to cut yourself with. Cuts paper and card stock easily. Pencil-style, with a cap. A boon for crafters, and a blessing for junior crafters.

That knife looks interesting, but it has been my experience with ceramic blades that they chip or break easily despite the claims of the supplier for the blade's endurance. They are very sharp and cut real good until the chippage or breakage occur.

I have ceramic screwdrivers that are used as they do not conduct electricity, you have to be very careful though or they will snap at the tip. Ceramic cooking blades are sold everywhere. I know the stuff can be dangerously sharp. I guess to cost ratio would be the deciding factor. I think that pen would be great for the light inscribing metal.
