Crucible CPM S35VN

Wish I had more info as well. I have some on order though. Somewhere around .160-.176" thick. I'll either be making some mid-large sized fixed blades or some thick kitchen knives :D. J/K about the kitchen knives though.
 
Seriously from what little I've heard is from another forum which is that it has niobium and vanadium, is easier to finish than s30v, and is tougher than s30v. I would imagine that it should take a good edge but in comparison to s30v I don't know as I haven't personally used it yet.
 
S35VN would be improved S30V with Niobium.
Niobium is a grain refiner and carbide former.
I'm told European steels already use it for years.
Examples: Becut, Niolox, RN15X ...
Seems to be like the RWL34 - 154CM story
 
We'll get info from Blade show. Chris Reeve is using it for their kitchen knives. Columbium [niobium] acts like vanadium in steel.

Awesome. :thumbup::thumbup:

I saw the poster behind him and I'm really itching for some Military's in it. :D
 
I think Chris Reeve made a very limited edition run of the Umnumzaan with it, under the name "Mystery Steel".
 
Only if you grind the dust and inhale it. Then the vanadium can accumulate in your organs and adipose tissue. In minute doses, it seems to help insulin regulation... ...or so the supplement companies used to say.
 
I wonder why they don't use titanium, it forms carbides like crazy, or so I read in an old book.

What is disturbing and why?

Your knives that contain Vanadium in the alloy are NOT toxic.

Like Thom said, If it doesn't get into your system it has no effect.
- The vanadium in your knives is mostly tied up as Vanadium Carbide. NOT the same reactivity or toxicity as the compounds discussed in wiki.
- And the Vanadium is in the knife. It does not magically dissolve and go into your food. Which, even if it did, the article says that ingested compounds are poorly absorbed.

You know fella, darn near everything is toxic in the right form or concentration. That even applies to straight iron.

On the other hand. You can't be too safe. Better send all those toxic blades to me. That would include all your steel blades. Wouldn't want you to get iron poisoning.
 
No one has to worry about their knives with vanadium in the blades. Be careful if you use a grinder to do your sharpening.

AH! thank you for pointing this out. I'd best be wearing my respirator when sharpening s30v.
 
For a knife maker, I would be more worried about grinding some of the handle materials. Carbon fiber is particularly nasty, similar to asbestos.

There are so many toxic materials used in knifemaking. Vanadium is just another one. Take proper safety precautions and everything will be fine.
 
I know Columbium was used in the barrels of some electro-particle guns at White Sands. High heat/friction tolerance.
