ZDP-189 vs S30V

Sodak I do agree with you on the forums being a great place and full of great information, :) and bs too. :) However, haveing some personal interaction with other people rather than a computer screen is just one. It's also kind of hard to handle, hold most knives, like you can at a show by reading posts. I'm sure there are many more reasons to go to a show but as I've only been to very few shows I'm probably not the best one to be answering.
 
Ok, now I have tested Sodak's Busse in INFI on the twist ties I was babbling about a few pages ago in this thread. Even the INFI chipped on those little twist ties! Barely visible by eye, but easily seen under magnification. It did much better than the Manix, Endura, or CRKT (a LOT better), but it still chipped. Under 100X they are fairly large chips, and by the naked eye you can see them if you look close. I used a wooden cutting board and push cut straight down into it. That wasn't enough to finish the cut so I tried rocking back and forth while trying not to laterally load the edge, but it ended up taking a few slices to get all the way through. Even turning it over and trying to pushcut it again before slicing didn't help much. I did this a few times, in different parts of the blade, with similar results. My conclusions are as follows:

1. My technique still sucks.
2. I need a harder cutting surface, as I think the twist tie just wanted to sink into the cutting board instead of letting the knife cut right through it (I know you mentioned mild steel Cliff, looks like I should have listened to that, but I didn't have any handy). Actually, I know it was sinking into the cutting board, as you could see a little denting in the wood. Maybe I can use a oven tray (or whatever the hell they are called) that is metal when my wife isn't paying attention and that would work better?
3. I should try chopping it with a hard wood background, but my daughter was sleeping at the time so that will have to wait.
4. I'm glad I didn't use the Jess Horn or U2 for this purpose, as they may be a mess right now, as obviously my technique still sucks.
5. I really can't blame my Manix for chipping on this, as I used MUCH worse technique when I chipped it and the others out.
6. Sodak, the men in white coats should pay you a visit for loaning me your knives!

The chips are small enough that with me not knowing how to use macro on my camera I would never get a good photo. I need Kel aa's skills so I could show these to you, but it isn't happening. The chips will easily sharpen out, so there are no worries there. Anyway, the INFI's chips are so much smaller than the other's there really isn't a comparison, but it did chip, and using much better (though still crappy, apparently) technique.

Since this has came back up. I used a VG 10 Calypso Jr, a Benchmade Leopard Cub ATS 34, and a Queen #11 D2, all sharpened at around 10 degrees per side, to cut one of these wire twist ties commonly found holding toys to there box. No damage to any of the edges at all. I set the tie down on a plastic cutting board placed the tip of the knife down in front of it and pressed down with the knife. All three knives cut through like a hot knife through butter. I was truthfully surprised how easy it was.
 
I noticed this also when thinning down some edges. Now use the same knives to cut through old carpet and look at the edges and you'll notice that they don't hold out as long as when a bit thicker. Its nice for some mediums when cutting but for others it deforms the edge quicker. Being that thin though they keep cutting nice for a while.

STR, I woould just like to apologize to you for the personal portion of my attack several days ago. It was uncalled for (personal portion only) and to be honest I only felt the need to personalize it because of your use of faith. I have a huge problem with that concept but I should not have taken that out on you. Again, I am sorry.
 
I did not interpret anything you said as a personal attack and certainly didn't take it that way but appreciate the apology. I read your posts again to see if I missed something and don't feel now that I was attacked and didn't then either. I do appreciate the fact that you cared enough to make such a post though.

Thanks

I've worked for years on stainless steels. Pitting resistance has quite a bit to do with Molybdenum content which ZDP has very little. It is balanced on the chromium side to form a high chromium carbide content and have a matrix capable of 64 plus HRC. A matrix capable of that hardness does not have optimum corrosion resistance. I have seen it's matrix carbon content in a report generated 18 years ago. It is stainless but it's matrix chromium content is just over this threshold. I'm not trying to bash the grade since it is truly unique in hardness and carbide content but that has a price. Heat treatable stainless steels are simple. You have Corrosion resistance, hardness, and wear resistance. You can maximize any two at a time at the expense of the other. You can balance all three for general purpose uses but are limited to the overally level all can go to at once.

What about CPM S110V? It is high corrosion resistance, hardness (Phil Wilson uses 64 rc), and wear resistance. Does S110V violate the rule?

Better questions are: 1)Did S110V exist at the time of that post? 2)Will Crucible continue to exist and/or produce S110V now that it has been divided between two entities without the service centers?

Enzo wasnt in charge of racing Alfa Romeos until 29 and didn't make a street car til 1947. there are no rusted Ferraris bult by the Commendatore in the 20's.

Yeah it was developed in 2006....

And yeah they still make it....
 
Current CPM S110V. :)
