Trying to learn about this material. I am definitely interested in comparing it to HIC that will come out in a Mike soon. Seems Scintered titanium goes back to 1973 but is this a new thing? They are using it in a blade steel. Non magnetic and supposedly beats some super steels in edge retention. What can you tell us about this?

Boker introduced knives in a similar material called Cera-titan back before 2000. There was also a kitchen knife maker called Forever that used it for a few years. It's been brought up here before in '07.

Thanks. From the info shared it seems to be able to be hardenable to mid 60s HRC. It seems like there is some interesting qualities to think about

Forever makes 2 versions of these sintered titanium alloys, and a couple of years ago i did a review of both with the help of a professional Chef:

The one with ceramic particles:

And the one with actual diamond particles:

https://www.bladeforums.com/threads/for ... t-18897603

The one with diamond particles is still in use with my elderly parents-in-law (non-knife people), they literally use it for everything and will not part with it.
Strong points for them: it is extremely light, it won't corrode ever, and it keeps a slicing edge for years in their kitchen.
They even use their thinned out knife to cut up butternuts for squash, something the actual Chef was hesitant to do, and at least so far the blade survives it.
Over the years i have thinned the blade just a hair more & put on a new microbevel just once.

Quite interesting for the diamond particles. I was suggesting adding diamond or boron nitride to ceramic blades for a few reasons. The diamonds would add the “toothy” edge like super steels with the added carbides because the ceramic is sharp but does not “feel” sharp and the added “toothiness” would add to the feel and performance of use especially when cutting things like tomato skins etcetera. The diamond titanium blade would be strong and have an edge that would last a long time. I wonder if the titanium wearing away and exposing diamond particles would add a micro serration effect.
