One step up from S30V blade steel.

Im looking for a steel that will hold an edge for a long time. This is my first knife with the S30V steel and it's a world of difference from my other knives with 8Cr13MoV, or 420HC. I've used this Buck for a few day's now and it's still razor sharp. My other knives would have to be sharpened 4 to 1 on this one! So far S30V amazes me how durable it is!
 
In general, but in this order of grades: ZDP-189 to CPM M4 to M390 to S90v just to name a few.

This has nothing to do with your post..... Do you go to SHSU?

Don't know if he goes to Sam Houston or not, but I bet he goes to Whataburger though.:D

In all practicality, when you have a Buck knife with s30v, there is no reason to go anywhere else.

+2 on the CPM M-4. That steel is really cool. It is a tool steel, and as such it is not "stainless". I don't care, I live in Nevada. In Houston, you will really care. I know Houston is SUPER humid. In the summer with Houston humidity, sweating, knife in your pocket, you WILL get rust on an uncoated blade. Luckily Benchmade makes a decent coating that seems to work. Since we ranch in East Texas, and I am very familiar with the environment, I would recommend you take a hard look at M-390. That steel is DARN nice stuff, and about as stainless as you're going to get. Without getting super technical about carbides being bound together and free chromium etc., just look at M-390 at 20% chromium. That's a ton.
 
being a tool steel isn't why cpm m4 isn't stainless. there are a lot of stainless tool steels, like m390.

but yeah, it's a pretty awesome steel.

I find S35Vn to be a little easier to sharpen than S30V, and it seems to take a somewhat finer edge. It is similar in those aspects to CPM154.

I agree that CPM-S35VN is a step up in ease of sharpening and finishing.

But I find CPM-S30V to be superior when it some to edge retention.

I find that CTS-XHP offers the best of both, ease of sharpening/finishing with the long lasting edge I associate with S30V, though the crucible steels do seem to stay at their ultimate sharpness a little longer then the XHP before settling in to long lasting working sharpness, especially if they have been sharpened to a highly polished edge.

In use all three of these steels make very fine knife blades.


This is just my opinion based on the testing I've done with these steels.
