Zdp-189

ok so if im reading this correctly everyone wants me to put it in the higher tier section, the reason im hesitent about taht is A: i have no experience with s30v or any of that level with the exception of vg-10 and 154cm. and B: im going off the sticky in the maitenance forum, i personally have not tried every steel listed and honestly cant even find a knife with 425m, so because of that i try to base my experiences off others which is a little sketchy but until i get a stronger income to expand my steel collection (of if anyone is willing to donate hehe) this is what i generally go by, plus im sure its a pretty old sticky so some things are bound to change

Why try to create a list like this of you dont have experience with the steels you're listing?
 
I don't really see a problem in trying to compile a "guide" based on others' experiences and input. I doubt there's a person alive who can say they've tried and tested every steel type from every manufacturer out there.

The caveat is that this is only a general guide. Something for newbies to refer to when they're looking for help.
 
ZDP-189 has always been good to me. I've got plenty of knives that have a ZDP-189 blade and I am extremely happy with it's results from cutting a steak, to stripping Al and Cu wire, and everything in between. I have had to touch up the edge on some of these knives, but I never had to work too hard to get the edge back to hair popping.

The knives I own with ZDP-189 steel.

Spyderco:
Caly 3
Stretch II

Kershaw:
Mini Cyclone
Leek
Shallot

Yuna:
Mini Hard-1 x2

AG Russell:
Acies

William Henry:
B12-TZ Spearpoint

I have found that the Yunas can take the most use before they need any kind of touch up. I don't know if it has to do with the edge geometry, but it takes a lot of use before they need to be put to the strops.

I'd really like to try YXR-7, but as far as I know, the only company that uses it is Rockstead and those knives are pretty expensive.

My advice would be to review and rank the steels the OP has experience with. To rank steels based on their reputation seems redundant.

Why? I'm a wanna-be steel junkie and the reviews and results of various tests can guide me on what I might want next.

Singularity, you misunderstood. I love reading steel facts as much as you!

I just don't see the use of ranking steels purely based on the info provided by others. We already have that info. My advice to the OP is to do some more in-depth write-ups of the steels he knows, rather than make a chart of steels he doesn't have experience with.

I apologize for misunderstanding. :D

What criteria are you using to "grade" these steels? Edge-holding? My list would be:

420, 420J

440a, 425m, 420hc, 12c27, Aus6

440b, Aus8, 8Cr13Mov, 9Cr18Mo

gin-1, ats-55, Aus10, 440c, CTS-BD-1

ats-34, 154cm, CPM-S60V, VG-10

bg-42, CPM-S30V, CPM-154, CPM-S35VN, D2

CPM-M4, CPM-S90V, ZDP-189, CTS-XHP


I added the steels I'm experienced with but left alone those I never used. The only one I can't classify is H-1. The PE and SE are so far apart in performance that I can't place it. I added 2 more "steps" in the chart.

I would rank 9Cr18Mo in the 440c group, based on my experience with it. It is also instructive that Sal Glesser stated that the reason 9Cr18Mo is not used on their folding knives made in China is because the contract manufacturer cannot work with it, although they can work the 8Cr13MoV. This distinction suggests that the two Chinese steels belong in different groups.

In your second to last group you put D2 with S30V, etc. Do you mean regular D2 or CPM D2? They are not the same.

Yup, they are the same - 9Cr18Mo vs. 440C steel composition comparison. To be precise, 9Cr18Mo is Chinse standard name.

They do belong to 2 different groups, actually I couldn't find equivalent to 8Cr13MoV steel.

I've read that 8Cr13MoV is the Chinese copy of Aus-8. It's shame that the Chinese maker can't work with the 9Cr18Mo steel since getting the Chinese Spydies and Byrds upgraded to a 440C standard would be a great improvement. I think Sal said 9Cr18Mo is the best cutlery steel available in China.

My use is based on a fixed blade I modified for kitchen use. And it's the 2nd best knife I have in the kitchen after the VG-10 Shuns. I agree about moving it up next to 440C.

I left out CPM-D2 since I've never used it. My D2 blades are all Benchmades and I don't think they use CPM-D2. Feel free to add it. :thumbup:
 
For me it's amazing.

MoreToasties - i do this becuase i havent actually tried a whole lot of steels being new to the knife community but if you want a list if what i have tried its as follows:

420, 440 stainless (pot metal)

420hc, 440A

aus 6, 8cr13mov, 440B

1095, 13c26n

VG0-10, 154CM, ZDP-189, Damascus san mai w/ Vg-10 core

now as you can tell thats a relatively scant list so i cant compare ZDP-189 to well to other as i have to sell most my knives to get the other ie sold sog vulcan to get the delica in zdp, so i cant do a side by side review but from what memory serves they seem pretty similar
