I am thinking about ordering a Brumby knife from Blind Horse but not sure which steel to get. Curently BHK offers these:

O1 Tool Steel

D2 Tool Steel

CPM154

CM154

12C27

13C26

S30V

440C

A2 Tool Steel

19C27

Out of those steels which is a better option for stainless. What is the difference between Sandvik steels listed how do they compare to s30v or cpm154. What is you take on D2?

Thanks

Better for what?
Compare for what steel characteristic?
 
The tool steals are not stainless.

As far as the others go it comes down to your use with the knife and ability/patience to sharpen the knife.

The S30V is hard to beat for an all around steel though.
 
Brumby is a nice 3.5" camping knife that would be good all rounder utility knife including food prep. I do not like O1 it rusts easily. I have a few barkies in A2 and it is a good steel but I would like to get something different. so my choice is between D2 (semi stainless) or one of the sandvic steels vs s30v (I have BHK in cpm 154).

So your main concern/standard for comparison is rust resistance?
 
What I want to know is

what is the difference between the 3 listed sandvik steels and how do they compare to s30v and D2 in terms of toughness, edge retention, ease of sharpening etc.
 
If stainless is the concern then S30V is the way to go.

It is also easier to sharpen(at least for a novice like myself) than the D2, so sounds like a no brainer to me.

There is no "best". Figure out what properties you need for your individual uses and find the steel whose properties are the closest match. (Stainlessness, toughness, wear resistance, edge stability, smell, machinability, etc)


I'd vote CPM154 because it's easier to sharpen, takes a finer edge, and has simlilar corrosion resistance compared to s30v and s35vn.
 
Love cpm 154 but already own BHK in that steel so would like to try something new.
 
If it was me i'd probably go with D2. It's an excellent steel and seeing as how i have no problem keeping my carbon steel blades up i wouldn't worry too much about rust resistance. After that i'd choose CPM154 mostly because i already own several knives in s30v and i'd like to play with it. but that's just me.
 
The Sandvik steels are pretty easy to sharpen and will take a great edge. They will wear a faster than S30V and D2 though. Between S30V and D2, both sharpen well and have very good edge retention. They are a bit more difficult to sharpen than the Sandvik steels though.

D2 does have a fair amount of chromium in it, just not quite enough to be classified as stainless. I've never had it rust on me, but I'm also not in the wettest of places.

Stainless?, eliminate O1, A2 and D2.


"Love cpm 154 but already own BHK in that steel so would like to try something new."


Eliminate CPM 154 and it's lessor brother 154 CM.



O1 Tool Steel ---> Eliminated

D2 Tool Steel ---> Eliminated

CPM154 ---> Eliminated

CM154 ---> Eliminated

12C27 ---> Easy to sharpen, good corrosion resistance.

13C26 ---> Easy to sharpen, good corrosion resistance, a bit more edge retention then 12C27.

CPM S30V ---> EXCELLENT EDGE RETENTION, BUT HARD TO SHARPEN ---> MY CHOICE.

440C ---> A good steel overall, but not as good the CPM steels.

A2 Tool Steel ---> Eliminated

19C27 ---> Compared to 12C27 or 13C26; better edge retention, harder to sharpen, less corrosion resistance.


Even though you ask for stainless you still inquire about D2: Great edge retention, hard to sharpen, not as tough as some of the others (CPM D2 offers a finer grain structure and more toughness). A great compromise between stainless and HC.

Great post Big Mike. :D


OP: If you've already got a superb stainless knife from this company, I'd try a non-stainless like D2 or A2.
 
19C27 is going to have more wear resistance than the other sandvick stainless steels but it will also get chippy in comparison if run too high and sharpened too thin. The pictures I've seen published of the steels and the grain size shows 19C as having much larger grain structure than CPM 154, and S30V due to the powder process used to make them.

12C and even 13C are pretty small grained and give good strength because of that. A bit more wear , and corrosion resistance than the tool steels ( not counting D2) with almost their strength. I wouldn't go this far, but it's been almost jokingly said that AEBL ( similar to 13C) is "stainless 52100". While I don't give it that much credit it is the basic idea. They are clean ( due to sandvik's process), have small grain structures with not that much chrome ( compared to 440C and some others) so they can do the high sharpness thing pretty well for a stainless. Recall 13C is a razor blade steel.

I still would take CPM 154 of the above stainless steels for it's all around performance and ease of sharpening. 440C would be my absolute last choice of all those listed.

If I couldn't have O-1, or A2, or even D2 due to needing, or wanting stainless I would go CPM 154, S30V, then 12C27.

Scroll down and read what Larrin has to say comparing these steels. Almost the same choice of steels: http://www.knifeforums.com/forums/printpost.php?tid/797292/

Lots more to read on this subject. It could take you months in fact. :)

I agree with Joe here, I would go with CPM 154 out of those steels listed.

If you've already got a similar blade in cpm 154 i'd go with D2 this time around. I think it really doesn't rust as easily as most people seem to think. It's not a stainless steel but it's not like the carbon steel blade on my case copperlock which stains if i leave fingerprints on it for more than a few minutes.

Here's another question for you guys: What are the practical differences between D2, O1 and A2?

O1 and A2 are pretty close performance wise, D2 is better edge retention and corrosive resistance wise.
