I see you have two different categories where S30V falls. Where does strider's S30V land? I know Chris Reeves would be in the lower catergory.

That might be an interesting question. I may be suffering from a [email protected], but I think I tried to find a comparison of ingot and CPM D2 on the Crucible website (in one of the datasheets) and never did find anything. If I missed it, a link would be great. I thought it was kind of funny, because there are comparisons of other near-twins such as 154CM and CPM-154.

It's about where regular D2 would also be right?

Strider doesn't make anything thin enough for me to test it. ;)

Per Strider they run their S30V at 59.5 RC.

That is about where I expected CPM D2 and 154 CM to finish. The CPM D2 might have done better if I hadn't used that Millie so much and had it start to thicken up like it is, but it never struck me as being better than ZDP-189 for edge retention. It has struck me as better than S30V, and it looks like the better S30V blades are in the same category as it, with softer S30V being worse than it. The 154 CM Rift at 61 RC struck me as being right there with S30V at 59 RC, so it would make sense that S30V at 60RC is better than the Rift while the Rift outperforms S30V at 58 RC. Thanks for the testing, it amazes me how much cutting and sharpening you get done in so short a period of time. This is a great thread for referencing how different steels perform compared to each other, and how the same steel acts much different at different hardnesses.

The D2 Military did fine, it started right at 15 LBS of downforce so it was right inline with the other blades.

They are all reprofiled to 30 Inclusive, resharpened after testing and ready to go. :thumbup:

I hope that with the aogami super blue mule being released that it will be tested according to Ankerson's protocol soon. :D

This sure is getting interesting Ankerson. Kudos!

I am thinking about getting one just to see what it will do.

I will have to get it RC tested though.

Any testings on CTS-XHP yet? My own opinion of the steel was that the edge retention was slightly less than S30V on abrasive mediums, but I sincerely hope I was wrong due to my having purchased an XM-18 in the steel:rolleyes:.

Haven't tested it yet.

Nice! and as I said it's getting more and more interesting. :D:thumbup:

Might be. :)

i believe it would be nice if formites able to do so would send jim 10$ or so to cover some of the testing expenses. his situation has far surpassed the tests that i did on cardboard & knarfengs tests on 3/8 sisal. tests using thread & cords while informative are negligible in expenses.

Thanks for the sharpening, now I can have something to reference and shoot for when I sharpen my own blades! You really are a testing machine, I don't know how you still have any arm or elbow nerves and ligaments that aren't causing you crippling pain after all of that cutting. After I get my latest shipment back from getting hardness tested I'll have to shoot you a message to see if any of them jump out as good test fodder.

I didn't go crazy with them, but they will all slice through TP clean easy, took them back to my testing sharpness standard. :)

Well, your quick and dirty edges are way sharper than most people can comprehend, so I look forward to trying them. I know what you mean about not going crazy with them, because I've spent an extra hour before trying to get every last shred of sharpness I can get out of a blade that is already hair whittling sharp, and in the end I go and make a couple cuts with it and that extra hour of time spent getting it showoff sharp is wasted because it instantly drops to the same sharpness my mere hair whittling edge would have achieved after those couple cuts. With a lot more practice on the Edge Pro I should be able to at least get close to your sharpness, which should be good enough to break down a box or two. :D

Yeah you can get the edges to that crazy level then make one or 2 cuts and it gone. :D

That's why I just get them to TP slicing sharp, I can take my Para 2 in S90V and slice a bunch of paper etc with it and it will still slice TP clean after.

Great stuff Jim, that list is really filling out now. I think CTS-XHP will be a welcome addition...

I think I needs to get me a Gayle Bradley ASAP.... :D

I am sure I will cross paths with XHP one day and test it. :)

The GB is a very good strong knife. :thumbup:

This is very useful information - thanks.
In my very limited experience, necessary edge retention depends on what you want to cut. For work in the kitchen, VG10 blades keep an edge for a much longer time than I really need. I have a Spyderco Yang in VG10 that was stropped after almost a year of frequent use, and didn't need sharpening on a stone for about 1 1/2 years. The VG10 blade works fine for me in the kitchen, and I can't really tell the difference between edge retention on the Spyderco VG10 and Gerber's M2 blades. Both steels have edges that say sharp much longer than my kitchen knives in 440C.

For cutting up sandpaper into squares - yes I did this once - the only thing that worked for me was a Japanese marking knife with a very hard laminated steel.

I haven't gone fishing for some time, but I hope that the next time I do, VG10 will work much better for me than blades in 440C. I wasn't happy with the edge retention of 440C when slicing up fish. Fish bones seemed to rapidly dull my knives in 440C.
