M4 Vs 3v

[bdmicarta]

4V is also less corrosion resistant than 3V

I thought 4V was less tough than 3V but with better edge-holding which makes it similar to M4.

Dan is all about the Vanadis 4 E now. He used his new comp knife in Vanadis 4 E at my hosted Mid-Atlantic cut back in March and won the nationals in Dallas with it last month. BTW, Donovan is using convex ground comp knives now. I showed him my method on convexing back in March.

Thanks for the info.

I actually like 4V more then 3V. It can handle the abuse same as 3V. Corrosion resistance is not up there with 3V but edge stability is great. Big Chris made a competition knife out of it and it performed great.

3v is the toughest, but won't cut as long as m4

M4 takes a very aggressive edge and is easy to touch up just don't let it go "dull" dull.


4v is an excellent blend of both 3v and M4.

Seems to have a very similar edge retention to M4 but is much tougher even at higher hardness.

Not as tough as 3v but still has a high level of toughness and more edge holding then 3v

M4 seems to take a more aggressive edge then 4v though.

4v is the least corrosion resistant out of the three.

CPM Cru-wear is similar to CPM 4v but takes a better edge and is less reactive but 4v is tougher at higher hardness

My choices if I could choose would be either Cru-wear or 4v


But the steel is only on component to many factors.

I was talking about corrosion resistance, not toughness or edge holding here. 3V is tougher than 4V, and more corrosion resistant, but less edge holding. Someone said that 4V is an excellent blend of 3V and M4, and I would have to agree, very good blend.
PD1/Cru-wear/Z-wear are also a fantastic family of steels, I love my PD1 and cruwear knives!! They are very tough with great edge holding, edge stability, and still have pretty decent corrosion resistance.
But, with all steels, heat treatment and blade geometry play a very big role!!!

The only problem of 4V is the corrosion resistance is pretty close to plain carbon steel. It will patina very fast cutting sour fruit like mango or meat.

3V is the best blend in every aspect, great edge holding, tough and very good corrosion resistance (better than D2 from my experience) when HT with low tempering method.

The testing I've done with 3V and 4V showed similar results. No edge issues with either steel in hard use testing. I HT/cryo using the low temp tempering for both steels.

Need to try low temper V4E (same as cpm4v). Here in Europe makers are reluctant in using low temper with this steel.
