What is the most wear-resistant steel for pocket knives

I know convex edges are supposed to last longer, what about a chisel edge, would that make any difference? I know a microbevel can make a huge difference.

A convex edge can hold up longer for some steel types. If you watch some of the videos on Cedric Ada he has done a test between convex and v grinds and some steel for v grind lasts longer. However the convex edge can often times still cut, it just looses its initial sharpness, it can't paper cut anymore if that makes sense. While a v grind will just go dull and not cut any more. At least from the testing he's done.

This changes with different steel. It seems some steel is much better with a convex while the higher carbide steels prefer v grind. Then again this could be due to a more course grind on the v edge vs the more smooth edge on the convex for those higher edge retention steels. Need more data points. U don't have all the answers.

Micro bevels are very good idea on these high carbide brittle steel types also. They will help prevent chipping.

What you cut also changes the edge retention of that steel depending on all the other variables/variations too.

It isn't so much that I wanted to imply that S110V and Maxamet have the same wear resistance when I said you should base it on how much you value corrosion resistance. It is more that they are just both very wear resistant. It is about practicality vs bench racing sort of. It is like asking which pepper is hotter becasue you need a hot pepper, an orange habanero or a red habanero? They are both super duper hot and they will both give your food the heat it needs (or doesn't need ;) ). Sure one is hotter but in a practical sense it probably doesn't matter. They will both get you the end result you want.

This.... very well worded/explained
 
Maxamet, 10v, A11 etc will rust. But it's not like you can't oil the blade. I use fluid film and have zero issues with rust on these. Sometimes I'll re oil after a long cutting session tho. Maxamet will patena and I find doesn't rust easily. A guy on Instagram even coated the blade in salt and it just patinas. When he went to a hot water spring with other minerals in the water it rusted. I dunno how helpful that insight that is. I don't have any patina on any of these alloys yet as fluid film does a great job and I keep them dry.
 
Just a question about patina then. Rust impacts the sharpness of an edge. How is this with a patina? Will this impact the sharpness of the edge, too, even if it is only a little bit? Or is it purely cosmetic?
 
From what I've read , Maxamet , S110V and M4 seem to be top shelf. But I'm not a fan of patina or rust so I don't even consider buying M4 or Maxamet.

From my experience , S90V , 204P and M390 all have superb edge retention while taking a scary sharp edge.

I also agree that , although somewhat commonplace these days , S30V takes a fantastic edge and holds it well for a long time.
 
Cpm 10v (same as A11) and CPM s110v
after those m390,s90v,m4

cpm10v and m4 are carbon tool steel ,it will rust , if you dont like patina buy them in acid wash finish only.

m390, s110, s90 are stainless .
