V-2 or ZDP-189?

[Luke2236]

I have a Delica in V-Toku 2 and really like the steel,but I have not seen anyone do a comparison to ZDP. I have the stretch 2 on on preorder in V2 but I’m really thinking about just getting a stretch in ZDP instead. Basically I would like to know how these two steels stake up against each other in use,edge holding and sharpening.

V2 is basically a non alloyed steel. It will behave like 52100/O2 and similia. I don't know the hardness but i can guess it's in the ~63 Rc range.

ZDP189 is a ultrahigh Carbon/Chromium stainless(so to speak) steel(so to speak).
According to Larrin it has ~ 36% carbide content; i don't know so much about that but it's obvious that it will behave more like a ceramic than a steel.

They have nothing in common. Neither V2 or ZDP resist rust and/or pitting; ZDP has a wear resistance way higher than V2 and V2, despite having a pretty high hardness will be surely tougher than ZDP.

V2 can hold (ultra)low angles way better than ZDP; throw a ZDP knife under 10 dps and you could have severe chipping even in low stress environments.

Both sharpen pretty easily if your benchmark are high vanadium steels.

Thanks!!! That helps a lot. I appreciate it.

Dying for that stretch release....

Hi Luke,

Where did you get a V-2 Delica?

I think that 36% carbon in ZDP is in error?

Not carbon, but carbides.

I got the Delica from st nicks knives. They are my local brick and mortar knife shop. It was the last v2 they had in stock.

[legOFwhat?]

V-Toku2 Endura maybe?

[Luke2236]

I’ve thought about the Endura but if I’m going to get that large of a knife I might as well wait on the stretch or buy a stretch in ZDP.

Takefu V2 is related to V-Toku2 in much the same way as Hitachi White 2 is to Hitachi Blue 2...

The Spyderco Sprint is in V-Toku2, which pretty much splits the difference between Hitachi Blue 2 and Hitachi Blue Super as far as carbon and alloy content.

[Luke2236]

I’m very familiar with hitachi white 1,all my carter cutlery knives are in that steel and I like it a lot,I’ve never had anything in blue steel. So far this little Delica is impressive. Today is its third day of pocket duty and it has done well. This evening will be a real test for it though. I have to finish bailing hay and this old bailer we have is known to mess up the twine. It should see a good bit of use this afternoon.

I like the ZDP 189 better. Takes a more aggressive edge and cuts longer

[Sjucaveman]

Zdp is crazy, I love my dragonfly 2 in zdp-189.

Ditto.

It's the knife that really kicked me into Spyderco obsession. I have three of them (backpack, car, desk), and I've gifted three more to family.

I feel like all the cool new Golden supersteel offerings are overshadowing it, but it's really an amazing knife Even the Chaparral, which I also love, can't displace it in uses.

Did you miss the Sprint, too?

I must have. :confused:

ZDP189 is a stainless steel that resists corrosion just like other stainless steels. Is it the most corrosion resistant stainless? No. Is it on the level of D2, much less 1095 and O1? Not even close.

Three years ago it was common knowledge ZDP is stainless, now people here keep spreading this rumor? :confused:

I've read that despite huge amounts of chromium it's believed so much is bound up forming the high carbide volume that it's not free to create the chromium oxide layer. It certainly isn't as corrosion prone as 52100 or m4 but I have had it develop slight removable surface rust in sweaty pockets.

That's exactly how my stainless steel blades behave. My carbon steel knives will patina in those cases, stainless steels get mild surface spots I can wipe off with my thumb.

Zdp is stainless in a commercial sense.
With the right ht not only all Chromium is bonded in carbides, but it contains also Cementite.
Spyderco doesn't harden it how it should be hardened, because Zdp was created for reaching expressly 67/68 HRc.
