    Aye. I hear ya. It's like carbidized titanium knife blades, being more gimmick than something I would ever "waste" money on.

    That's a tungsten carbide knife. There are few different types of carbide, silicon carbide can be turned into an extremely hard ceramic but it's not used for knives it's used mostly for abrasives. Most ceramic knives are made of zirconium oxide and should never leave a kitchen!

    Yes, it's tungsten carbide, I know. There's a ton of different carbides out there, and when used as a knife blade they're all going to run into issues with being almost entirely unable to withstand side-loading or impacts with small, hard things like bones, staples, etc. and be difficult to resharpen without micro-chipping. Zirconium oxide is generally used for ceramic knives specifically because it's one of the most tolerant of ceramics to the sorts of things that generally cause ceramic knives to fail, but even then, they're quite fragile.

    best place for ceramic blades to stay is the Operating Room. The brain surgery ceramic blades are less than a mm long and in many cases way smaller.

    That finger guillotine looks like it would come in handy if bored!

    My wedding ring is tungsten carbide, and brittle (at least from my experience with this particular ring) Dinged it on a rail this past summer waiting in line at a theme park and it took a little chunk out of it KIMG0184.JPG
