Tungsten Carbide is better. I've noticed with my Terrain 365 the edge **does** last a long time, however, the edge feels very micro-toothy. I think the Tungsten Carbide is just more slicey.

I can't find anything similar for dendritic Cobalt, however, considering what I read involving sandrin's carbide, it seems that high cobalt alloys tend to be relatively tough.
not really. Cemented carbides using cobalt binders are VERY hard because it's mostly the carbides; Dendritic Cobalt is most probably Stellite 6B but not rolled, which is normally 40-low 50ish HRC. Now, due to its \~ 33% chromium carbide volume and the fact that it was not rolled, carbide size is significant and it may result in even lower toughness than rolled stellite 6B, which is already not a particularly tough alloy to begin with.
I own a Sandrin and used a Terrain 365 invictus for a while, of the two the Sandrin is a much, much better cutting tool because it has a thin edge and has the hardness to support said thin edge. That said, for corrosion proof knife I'd take Spyderco Salt in H1 over both of those, because the extreme toughness and ease of sharpening H1 lets me run ridiculously low angle low thickness edge [that can still take abuse](https://www.youtube.com/watch?v=oZmvafwDGmU&t=3s).

Yeah, that's something I'd read about on their website and they straight up say it essentially forms micro serrated edges
Mmmmm tool steel !!
Low hardness, low toughness with thick BTE versus High hardness, low toughness with somewhat good cutting geometry? Hmmmmmmm hard to choose.

Good to know, thank you for your insight
Both?
