Asi (from guns.ru) sent me his testing result for CPM 10V by Phil Wilson

743650.jpg


999 times it cut that rope, then he cut wood, chop frozen chicken and finally whittle nail. Only damage he found after nail microscopic bend on the edge - wave like which he fix with two-three swipes of ExtraFine diamond.

Second place INFI (Busse) - 300 cuts and third place YXR7 (Roakstead) - 250.

Thanks, Vassili.
 
I have wanted a CPM10V knife by Phil Wilson for sometime now. I remember Cliff Stamp doing a review sometime ago on one of Phil's knives in CPM10V and he seemed to like it a lot.

Phil's knife has a higher hardness, much higher levels of vanadium carbides, and a thinner stock grind than any INFI I've ever seen, so I'd expect Phil's knife to do more of the mentioned tests.

Hope that wasn't too brutal for you. ;)
 
This is pretty much top shelf knives and steel all around. I can't read russian so your brief explanation of events is all I can get so I hope you don't mind a question or two Vassili.

The Rockstead knife with it's super high speed steel should have been set up from the factory with the smoothest, most well polished edge of any knife on the market. It was essentially set up for push cuts & slicing. Were the edges reprofiled or resharpened or in any way modified?

Mr.Wilsons' 10V doesn't surprise me. Likely 15V or one of the other biggies like Rex 121 would be it's only real competition.

I'm surprised at the lower standing of the YXR7 in comparison to the Infi. IMO, it's almost too sharpened or, more likely polished to have the mini serrations that is needed in these type competitions.

Can you tell us what the stopping point was? Was it pounds ( over 30 lbs for instance).

Thanks for posting this Vassili. This is the first such test with the Rockstead that I've seen. Joe
 
sorry for the late answers! I have all this week a project meeting and do not have a lot of time for the internet o testing!

1. I used Rockstead SHIN with YHR7 without reprofiling the geometry is thicker as the knife from Phil. that is why the so low amount of cuts.

2. the knife from INFI (Scrapper 4) were reprofiled to 25 grad on the cutting edge but anyway it is thicker as knife from Phil. it is most universal knife of mine.

3. the geometry of the knife from cpm10V from Phil was the thinnest - that is why so many cuts (and of'cause because of super steel and heat treatment) but it is not the chopper or camping knife just a pretty small friend of mine to make kitchen work, and pure cuttings.


I found that the most universal knife is the knives with INFI! YES I am the INFIHOLIG! :) I do with the knives from INFI everything I can do at all! I allready broke one of them (Game warden) And I think that the INFI has the most impressive COMBINATION of the properties!

the edge of the rockstead was not too polished;the low standing of YHR7 - the thicker geometry and convex edge

stopping point - for the normal knives - stopping point is after 50-70 cuts, after that I cannot cut anymore.

for knife of INFI the stopping point - I could cut even more, and I think now I should have to do it, but that time it was already a record for me and I stoped.

than later I got the knife from Phil and during the cutting tests there were no "stopping point" also. and due to the thinner geometry it was easierer to cut with the knife from Phil than with any other knife.

so the results of this tests - I do not want to compare cpm10v to any other steel (not now) there are too many differences in geomety of my knives to compare the steel itself.

I just want to say - I am very impressed with the cpm10V from Phil Wilson and it is not So brittle as I thought before. :thumbup:
 
Do you think the YHR7 was maxxed out or could it still produce numbers closer to 10V with the same thickness and geometry? I don't mean to be annoying but that steel is still relatively unknown here and I've been curious for awhile about it.

The micrograph on the Rockstead website has the smoothest, most mirrorlike blade and edge on any finished knife I've ever seen. Like telescope mirror smooth.

On the other hand Rockstead advertises the ZDP/ATS34 laminate as being the sharper of the two, with the YHR7 being much tougher.

Thank you for the time and testing. Joe
 
I tested the ZDP189 on the same rope and with different blade geometries - no more than 95 cuts.

I do not know if the YHR7 could make the same number of cuts as cpm10v at the same geometry.
 
i loves me some cpm10v now that i have worked with it (jsut get all the grinding out the way before heat treat)

and yes it is less prone to chipping then i thought too. was phil"s knife at 63Rc
 
While American knife manufacturers ignore this American made super steel and moves production to China, I started my little project:

I do not need all this fairy tales about "good enough for our customers" cheap and easy in production (and very profitable) steels and also their concerns about my ability to sharpen this hard to sharpen blades...

I will make my own knife with CPM 10 Killer V steel!

Some readings on the topic:

Yes it is expensive and I have to save every cantimeter of it, but I will have two exceptional knifes in result:

Thanks, Vassili.

This is an attitude championed on rec.knives for a long time. "No one makes what I want, so I'll do it myself." Keep up the good work, as I remember your knife from A2 from a while back, w/ brass guard and cocobolo handles. I'm bringing this thread back because I want to know how progress is going. I'm still hoping to soon make myself an S7 machete, and an A2 version of the old Cold Steel Scalper pattern at about 64 HRc (high hardness toughness peak). I'd also like to make myself a balisong using high temperature hardened (tempered at ~1100 F) M2 HSS at 65 HRc. Folders are a while off though, so the machete seems simplest to start. I'm sure I can sharpen the higher hardness stuff, no worries.

It is going. I am not in the rush. Sander belts does not work very well on this steel, I take different approach with all precautions knifemakers told me and doing this very carefully and slowely. I grind about 25% of the blade now.
