The hardest knife in the world

and with highest edge retention is mine knife After two years scratching dishes it still cut paper , more data about knife here........... https://www.bladeforums.com/threads/san-mai-with-tungsten-carbide.1746640/
Now seriously, for easy use it would pass. Why don't they make them? We have ceramic knives, they are more brittle /I think that at least / so they produce them? Tungsten carbide is probably more durable and would last longer ?

Every steel is a compromise.

If there was one steel that was good for everything, there would only be ONE steel.

A lot of people are talking like MagnaCut will be the second-coming, but I agree with your sentiment completely.

Tungsten carbide is used on drill bits and trekking poles, very hard stuff, but I've never seen it used for knives. Maybe Larrin can weigh in here.

See Sandrin Knives. This is a tungsten carbide blade. Guess what, it gets dull.

Those tungsten blades are supposed to be quite the experience; especially when it's time to sharpen them. I seem to remember them being unlike anything else to sharpen and a hell of a lot of work.

I know about them ,but they are only 70 HRC .This one is 84 HRC .Everything will dull , even diamonds ,but question is when compared to any steel ?

This question cannot be answered - too many variables.

- What knife are you trying to compare it to?
- What are you cutting?
- What force are you cutting with?
- What is the edge geometry/angle?

The profile and tempering of the knife just as important as the type of steel you are trying to compare it to.
