ddornGood call, upon further reading this does sound similiar.
I have a Boker Ceramic and a CeraTitan and I can't say I'd recommend either as an EDC for most users, at most a show off knife or maaaaybe a suit and tie letter opener.
ddornThis is an article I found about the knife: https://gearjunkie.com/vargo-sobata-titanium-ceramic-knife-review
While they explain the chemistry behind it, they do say that while they are using the knife, they do have remind themselves of why it actually works. From the article, it sounds like they are relatively impressed by the knife, but cringe at the price.
