Some Justice to ZDP 189

Once again, no. If your tenacious doesn't get "really dull", then no. You may disagree all you like but if you can't "really dull" 8Cr13Mov, then you just made my point. If you can't "really dull" 8Cr, then that's probably all you need.

All you really need to say is that you just want the steel and I'm done arguing with you. But when you declare that you need the edge holding for your uses and in the same post say you don't "really dull" a tenacious or just dull it enough that the brown rods can bring it back in a few minutes, I will call you out about your needing supreme edge holding for your uses.

That's with only brown SharpMaker rods though, and I do intend to buy some diamond rods for my SharpMaker to more easily facilitate sharpening of all my high wear knives. I CAN justify it as is though because in a day of work for ME, cutting rope/cardboard/plastic/vinyl and/or rubber tape/fiberglass it won't get dull to the point where it would be prohibitive to get back to hair whittling...and because the coarsest grit stones I have are the medium grit SharpMaker stones, that works for me. If I was to skin an Elk or a Moose (And was forced to choose just one knife), I wouldn't choose my Caly 3/3.5 or ZDP Delica...but that doesn't fall within my usage parameters and neither of the 3 knives would be optimal as far as size and geometry anyways. Everyone's usage parameters are different, which ultimately means there's no one single "One size fits all" answer for me to give you. I like ZDP on my knives because I don't have to sharpen them often...if it takes me 90 minutes to sharpen it on the brown stones because I needed to do some abusive cutting I didn't plan for, so be it. It would be a lot faster on diamond stones, but I've only had my Caly 3.5 get that dull once, and the ZDP Delica close to that once (That took me 50 minutes to get hair whittling). I don't mind though...if I was to do something really intensive I'd take my CruWear Millie and 204P Para2 (As well as one or two others if I deemed it necessary like my CruWear Manix or Schempp Tuff... Spydercos carry easily after all) and the ZDP would hold a working edge longer than the lot anyways. Forgive me for not feeling the "Hate" of ZDP-189, but I do like the steel. The one knife I use most often with it is my Caly 3.5, and it's more of a gentlemans/dress knife IMO, and it's main uses are opening packages, cutting rope, cutting up food at lunch, and cutting up cardboard boxes...nothing which typically will stress it to the point where after a day it will take me more than 5 minutes to touch it up to hair whittling. Would it be my first choice of knife to bring 400 feet up a cell tower with me? Probably not...I prefer my PM2, Chokwe, Military, OD Goddard, or SB Stretch for those tasks (And my Swick3 in Kydex sheath attached to my harness as backup). Up a tower, I'll mostly just have to cut electrical tape, after cutting open antenna boxes on the ground, and fiberglass straps and zip ties. Potentially rope too, but not typically on a job site as we bring and prep the rope we need before going to a job site. I've carried my Caly 3.5 at work, and though it's not my preference before any of the knives I listed above (For reasons other than the blade steel), it still performed well and never took me more than 10 minutes to resharpen because none of that classifies as "Abuse".



There's no "One size fits all" solution...I'd rather have my Caly 3.5 in said role than my Tenacious because the Tenacious would be dull (Not "Really" dull) before the day's end...the Tenacious makes a great beater knife because I have no qualms about cutting directly into metal with it...but I don't expect it to hold an edge, so it gets used for abusive cutting tasks, while the Caly 3.5 gets used for more conventional cutting, as do most of my knives...the Tenacious and my S30V PM2 are my beater knives and take the most edge damage as a result (When I know such things will happen, but I'm not afraid to use ANY of my Spydercos hard if/when I need to). If you're keen eyed you'll see which model I listed above is in the picture I linked...and I've sharpened it a number of times...it's had edge damage and did take less time than ZDP did to fix, but I still wouldn't have called the process "Easy" with only the brown rods). Everyone's uses may vary, as will everyone's sharpening equipment and personal abilities. I certainly don't see the need to be afraid of ZDP, and I'd gladly substitute most of my VG10 blades for ZDP-189 if I could because I like the steel, but that's MY opinion and I'm by no means telling you yours should be the same...just that it's my opinion. I absolutely respect and encourage you to disagree with me if that's your true opinion.

edit to add: back on the topic of ZDP, I think it's fragility is often very exaggerated by people simply because they've heard it on forums enough. Which is especially funny when people talk about the toughness of s35vn or Elmax, because they've heard THAT mentioned enough. When these are all high carbide steels, not tough by a long shot. But not glass, either.

This exactly...no reason to be frightened of it and too many people trying to scare people away from trying it.
 
Someone correct me if I'm wrong, I think Spyderco was the first production company to use ZDP on the sprint run Delica with powder blue handles quite a while ago. That run of Delicas had their ZDP run at a very hard rockwell. Probably something like 64 or greater. The result was supposedly (I have not experienced this with mine) a chippy blade and it was an absolute MOTHER to resharpen. Since then they've toned down the RC for the british racing green production versions.

that's what a couple of users and sharpeners said here (reduced to around 63 --which is little consolation for sharpeners, that's still harder than a file) but i haven't heard any confirmation from spyderco. all my zdp's are the green-handled flat-ground versions. for this reason i've been curious about the earlier saber-ground blue handles for some time now, and i'm actively looking for samples on the bay.

rockstead heat treat theirs to 66 and even 67 but they make stouter blades than spyderco (just from the looks of it.)
 
If ZDP is such an amazing/exotic/high performance steel, then why can it be had on cheapER blades?

Hank, there is one up for sale here on the forums.

Good price too, in my opinion.

What's your definition of "Cheaper"? I don't consider an $88.31USD knife expensive...and that's for a Delica...cheaper for smaller versions.

As for ZDP-189 kitchen knives...they can be hard to find and they tend to cost quite a lot more than anything Spyderco offers in a folder.

You're misunderstanding that. What GES said is that lot of people are scared by the supposed brittleness of ZDP. He really didn't say that it's easy to sharpen when it gets really dull. ;)

Since you're the one with the "don't let your knife get dull", it seems that you are scared of regularly getting it back sharp from completely dull.

If someone wants to try ZDP, let them get it for the right reasons. Not contrived reasons like yours. When I tried out ZDP, I had no illusions about needing that edge holding, It just came later when I had tools and knowledge that I had no qualms about letting it get completely dull.

I would say anything under 100 is on the cheaper side, especially for a super steel. That's exactly what i'm talking about, there are several knives for around $100 or less that use ZDP. Why can't you find anything in S90V or M390 for less than $100?
