S30v

Neo: Spyderco's Native is already benefiting from S30V, and it's damn cheap for a good knife.
It's not as common as 440A because total cost for S30V for the material and machining is far greater. Get over it. $50USD for a S30V blade is one of the cheapest going.

But there is a consensus S30V is great steel, and given all other elements are good, a knife would benefit with this steel.

It's a great 'all-around' steel for 'all-around' folders and smaller fixed blades (blade less than 5" or so). Specialized blades and larger 'all-around' blades can see better performance from other steels.
 
Datasheets from Crucible:


It's all in there. Pay particular attention to the bar graphs on the S30V and A2 sheets. It's not moonmetal, but it is pretty impressive for a "stainless."

Personally, I'm more excited about CPM 3V. Now that's what I call moonmetal.
 
Garageboy,this is a much debated issue. IMO yes BG42 takes a much better edge on a custom heattreat (CRK or Paul Bos,etc) My Buck 110's in Ats 34 and BG42 hold about the same.
 
Guy G,
Are you saying a Paul Bos heat treated blade has better edge than one heat treated by Buck?

O.K. this is a trick question because Paul does the heat treat for buck. In fact Pauls heat treat shop is in the Buck plant. :eek:

Aaaaahh CPM 3V I have to 3nd the 2nd vote for this great alloy. Because of it's toughness the edge geometry can be very thin which makes for great cutting ability. It can be very hard for great edge holding and still be tough enough. I still havn't tested CPM 30V against 3V, but stain resistance is the only factor that prevents 3V from being the ultimate. I doubt that CPM S30V will ever be able to do the things that 3V will. Hard to sharpen, what does that mean? If you care anything about cutlery you will own some diamond sharpening device. I have grown tired of the Hard to Sharpen Song!
 
While we talking about the different properties of the various steel, anybody care to throw in their comments on the merits of the INFI steel?

Don't seem to be able to find much info about it. How does it compare to say, CPM3V?

kee :)
 
I have a 110 rebladed with ATS34 , PCKS w/BG42, a 112 rebladed with BG42 and a Buck Taclight with Bos treated ATS34. The Taclight holds an edge longer and out cut the others in a head to head cut on 4" truck tiedown web strap.(i had this on hand it provided me with a constant material for testing.)My Sebenza w/ BG42 holds a better edge than the rest. (have not cut a pile of strap,so this is an opinion based on the fact i only sharpen the Sebby once every 3 months)
What I've said is nothing really new. There is lots of discussion on different results on the same steel.Dont forget that Paul is doing small batches and Buck is literally using a conveyer belt.
A couple of years ago CJ Buck posted a couple of charts from their CATRA testing that clearly showed that after 25 cuts ATS34,BG42 and 420hc were with in 3 mm of each other. 420 hc isnt that bad either.
Take care, guy
 
Kids found my notebook... 110 ats34= 53 cuts,112 BG42= 55, 110420HC=47,Taclight Bos heat=64.

Err, I mentioned fine edge retention, not just edge retention. D2 has a nice edge retention, but it becomes semi coarse

After two years it still seems to be an expensive high-end steel witch very few big manufacturers use. :(

Are you really surprised if a new knife with S30V comes out? I am not.

Swamp rat comes out with it, Spyderco has a handful of models with it, there are much more.

Guess, in about two or three years Kershaw comes out with it too...

Paul does the research and development for Buck. There is no way that he could do all their heat treating. When Buck receives a new batch of steel, Paul lets them know how to heat treat the steel for the best performance.

I'll agree with Cliff on this one. I've always shied away from carbon steels because of the climate in which I live (Duluth, Minnesota...humid as Hell in the summer and cold as the North Pole in winter), that is until I bought a Fehrman in 3V. It has enough chromium in it that if you catch rust early enough (or avoid it all together with Rem Oil), it's not a problem. It is VERY tough and impact resistant, and holds an excellent edge. If there is a wonder steel around right now, it's 3V. I will admit, though, that when it comes to stainless steel, S30V is top of the line. I have a Kershaw Random Leek, and I love it. But, when it comes to heavy duty knives, I'll choose 3V whenever possible (Ya' hear that, Strider??? Love some of your designs, but don't fully trust the stainless anymore)!
 
I have a Al Mar SERE with s30v and a KABAR D2 (with D2 steel), and the AL Mar is definetley sharper, probably a hollow grind, but, the Kabar wit it's D2 although it's not as sharp, cuts through the tough stuff much easier. I think it's safe to say that they're both great steels, and as long as you try to control the abuse, both will hold an edge and cut tremendously well fro a very long time and resist corrosion and do all the other things we want a knife to do, beyond what's considered normal or acceptable. :eek:
