Will CPM-S35VN replace CPM-S30V?

That sounds more familiar. I guess we will have to see what teh Native V has in store. That will be a good model to test with.
What do you think about the triple tempering on the Crudader Forge S30V?

Never got to play with it, but I do know if S30V is done correctly and hard it can be awesome. :)

i'm not asked but i think that whatever the tempering process on crusader forge's blade it won't cut anything because it's thicker at the edge than a freaking axe

That is true. I was wondering how that process would impact a blade with the geometry of a Spyderco Military or para2. The tempering and overall HT would ahve to be scalled based on thickness I would imagine.:thumbup:
 
The data sheets from Crucible for S30V and S35V show exactly the same heat treat information for both, same temperatures, same hardnesses, S35V data sheet appears to be identical to S30V except for a few comments about the tweaked chemistry and small changes in properties.

As Ankerson suggested, it may be less prone to chipping if not done precisely compared to S30V. I believe in addition to niobium, there is less vanadium and slightly less carbon. Those could contribute to slightly different heat treating properties. At very least there would be subtle differences, just considering the differences in chemistry.

It will be interesting to see where the steel choices go in the future...I hope they don't replace s30v across the board in the likes of the Sage, Millie, etc. Not because it wouldn't be cool, but because I'd want to re-buy them all in the new steel! :D

I'm excited to try out s35vn on the new Native
 
Someone posted the following in another thread, and it makes sense to me...for what that's worth...

Correct me if I'm wrong, but when Crucible gives a figure for "toughness" it has nothing to do with edge retention. It has to do with resistance to lateral force...in other words, basically (for our purposes) resistance to chipping when edge-prying.

It doesn't have to be prying, depending on the user experience level and hand steadyness, plus material being cut, we all apply various lateral loads to the edge, so do the irregularities in the mediums. Thiner edge == more pronounced effect.
So, it's quite relevant to edge holding :)

Quite frankly I find it odd that more manufacturers aren't considering CPM-154. Its American made, stainless, reasonably cheap and easy to work with and apparently it offers fantastic toughness and edge holding. Custom makers have readily embraced it and found it top notch. Scott Gossman tested it extensively and found it had excellent properties, and he's not a lover of stainless steels.

I think it had/has to do with the quantities available, from what I hear it's not the easiest steel to get in large quantities that the production makers would need.

I think it would be interesting to test 2 Military's, one in S30V and the other in S35VN, both at 60 HRC and see what the difference is if there is one.

I wouldn't be interested in S35VN below 60 HRC though.
 
what I would like to see is a steel chart comparing S35VN with M4
I understood that the Tuff may sport a S35VN blade (even though the proto was S30V) as per Ed's request...
 
I've started to use S35VN (the Mule released last year) a little for gardening chores (a mix of cutting string, plastic, some cardboard, small plants and sticks of different sizes, on occasion accidentally hitting wire and nails and digging soil, well, you get my point). For my uses, I noticed it still chips, but it chips less than S30V (a Para that I use for the same tasks) and when it does, the chips are substantially smaller than in S30V. It holds the edge better than VG10 (an old Endura that has been my gardening folding knife of choice), and I've been able to maintain it with as much effort. In contrast, S30V is harder to maintain than both VG10 and S35VN because of the larger chipping. No rust or pitting that I can see, even after working with it in very wet conditions and sometimes leaving wet and dirty on the bench until the weekend. So far, I'm liking S35VN better than the other two steels. My order of preference for all the steels that I've used for this type of tasks is S35VN, VG10, S30V, D2, A2, 440C, and Cr13... (I forget the designation, but it is the Mule that was also released last year), but the preferred knife is still the Endura because it has an useful combo edge.

i agree. below 60 HRC i don't really see a need for S35VN in most applications. IMO, a good spot for S30V is right around 60 HRC, S35VN is suppose to be tougher so i would expect it to be run around 61 HRC to have the similar toughness as S30V @ 60 HRC, but with more edge retention.

I doubt we would see 61 HRC in production blades, but 60 HRC would be nice.

Time will tell once production blades start hitting the market what hardness are running at and how they do.

i wonder what HRC spyderco ran their S35VN mule at?

i have a feeling that most companies will probably run the S35VN at the same hardness they are currently using for S30V.

do you have any plans to add S35VN to your list of steels?

If I can find soemone who his running it at 60 HRC then I will.

Or if some loans me one of the soft ones to test I can add it, I won't buy any butter blades because I have plenty of butter knives in the kitchen and they are cheap.

Would be interesting to see how it does when run soft then at 60 HRC.

I know there was a HUGE difference in S30V at 58 and 60 HRC, it was so big it was like testing two completely different steels.

I have a feeling that Spyderco will run theirs on the hard side like they do S30V. :)

If you are interested and don't get a closer offer, I can loan you my S35VN Mule. LMK. Best comms @ newellj at gmail. :)
