Hello I was wondering how corrosion resistant vanadis 4 extra is and how easy is it to sharpen. Also how does it compare to cpm 3v? Thanks

Don't have number values but I'd say not bad at all. Much better than O-1 and Super blue. Not as good as D2. Heat treatment given the knife can affect the corrosion resistance just as it can the wear resistance/toughness so two knives with the same steel made differently can have different results.

and how easy is it to sharpen

I find it easy to sharpen. The knife I have is a custom at rc 63 and it sharpened easy on diamonds and SiCarbide stones with burrs coming off easy probably due to hardness and other factors. In other words it's good.

Also how does it compare to cpm 3v?

Same class steel. More emphasis on wear resistance than 3V looking at the composition on paper but in real life I can't tell much difference. I would have to test like Jim Ankerson to notice a difference. Regular EDC carry doesn't present enough challenge quick enough.
 
Thanks Mastiff the knife I was looking at (zt 0180) has a rc of 61 I believe. And do you think it would be more corrosion resistant than 1095 because that's the steel most of my knives are in and I was looking for a step up in corrosion resistance. Thanks
 
I think vanadis 4e will be a step up from most steels in a lot of areas. I believe as soon as a big company like zt puts it on the market it will be seen as the new steel to use.

Battboy, I'm certainly no expert on the steel only having one knife and not all that long with it but my guess is if you are familiar with 3V, it should be as good, possibly better. Once again depending on the heat treat, finish, coatings? Stuff like that.

It's a good steel and I'm impressed with it. Of course I've been a user and supporter of Vascowear/Cruwear, Z wear/PD#1, 3V, family for decades, since there was only Vascowear on the market ( now discontinued parent steel of Cruwear, cousin of 3V, etc.)

It's not for everybody. I wouldn't class it with the true "super steels" ( S90V, S110V, 10V/A11, etc) as far as abrasive wear resistance is concerned but it has the combination of great wear resistance and excellent toughness I tend to like in steel for use especially in outdoor stuff ( Bushcraft, skinners, etc). I rarely use stainless steels and grew up with carbon steels and corrosion resistance is the attribute I put the least into when choosing a knife steel. Even so this class steel isn't bad and would be easy for "most" users to keep clean and non rusted. It's much easier to resist corrosion than with O-1, 1095, Super blue, White (shirogami) and saw/spring steels like Sk5 and 5160, or bearing steels like 52100.

There I go talking too much about a subject that could be answered in one or two sentences. :)

Good luck. I can't say you will or won't like the steel as your uses are different from mine but I'd imagine, as bodog does, that it would catch on pretty well with more familiarity and users getting knives in this steel, either Vandis 4E or 4V out in the woods.

Wonder why Knife Research only hardened their vanadis 4e to 60 hrc when it can go so much higher.

We can only guess. My guess is they won't get that much more wear resistance by going higher. They are probably also keeping in mind the future you tube videos of people hammering their stuff through hardened steel bolts and such like was going on with their 0100 in 3V. They have to take stuff like that into consideration.

That isn't the bad part. It's the guys that come on forums and swear up and down they just dropped a knife and it broke completely in half. There is the guy that always pipes in "it's a bad heat treat" as if they have some inside information. :)

maybe I'm cynical but I have seen enough stuff like that play out. The truth is though that only the insiders who make the knife and heat treat it know how, how much, how long, etc.

PM 14-2-4 CrMoV is S30V
PM 7.5-1.3-2.75 CrMoV is 3V
PM 14-2-3 CrMoVN is S35VN
14-4 CrMo is 154cm/ATS 34 (note: there isn't a "PM" in front of number which means "particle manufactured" or something meaning it's a powder steel.)
 
So then a non stainless S30V that's tough as hell. Doesn't sound too bad.
 
Pretty much I guess. It should be able to hold thinner edges and better geometry than S30V which should more than help make up the difference with S30V and it's little bit of advantage. If my experience with 4V is any guide anyway. My knife in 4V is rc 63 and still tougher than S30V at any hardness used in production knives I've ever seen.

Recall though I've never actually tried Vandis 4E, just 4V. I figure they are close enough for generalizations like I'm using. I know I like 4V, as well as the Cruwear/PD#1/Z wear type steels. You can essentially say the same about them from my experience. Example is the Cruwear Bow River from Phil Wilson at rc 63 I have that Jim Ankerson used in his testing. It beat out more than just S30V in abrasive wear due to it's toughness allowing pretty extreme geometry.

I have the ZT 0180. So far I am very impressed with the steel. I am not sure what they got the final hardness to in this run but...it took me a while on my Wicked edge using diamond stones to re-profile it. I sharpened it to 17dps and left it a little toothy by stopping at the 1000 stones. hht2 along the entire blade. Took it Elk hunting right after that and put it through its paces and let others use it. It holds an edge longer than my random leek sv30. It was used to process 4 elk and joint off the legs of them. So it hit bone and was twisted around in the joints. It suffered some damage at the very tip when someone was using it like an ice pick to get a joint to let go...was in the wrong spot...and the curved section of the belly. Just where you would expect damage with this kind of abuse. It was still shaving sharp at the majority of the flat portion of the blade. Even the damaged sections would only be noticed by someone with knife edge knowledge. It would still slice the crap outta rope. It held up very very well in my opinion. I would love to know the specifications to what they ended up on the hardness scale with this run. She is a keeper! It was never cleaned real well the entire trip and there was always contaminants in the sheath. So for say 6 days it was just wiped clean. No staining but when I got home I cleaned the crap out of it, resharpened it and oiled it for storage.
 
Zamfir, thanks. Nice post. Good to hear some feedback on real world use. The 0180 and its steel have had me interested.
 
I hope to give it some more abuse camping or something. Hunting is done for me for the year. Maybe I can hack some wood with it or something lol. When I resharpened it, I mirrored the 17dps bevel and then put on a 22dps mini bevel and left it toothy with a 1K diamond plate.
