No offense taken, the testor mentioned how far off a lot of people's testing can be due to uncalibrated equipment and bad technique, so it is a very valid point to bring up.
Mike
No, your explanation is OK. In my opinion, a huge majority of the problems with BLADE (not lock, etc.) are due to the bad HT. And, the RC hardness is a very good indicator for that. For example, somebody could try everything possible to sharp a knife which actualy has a low Rc. Frustrations, angry customers, etc.
I agree with 3% failures in QC. But, that is true for e. g., controlling locks too - in spite of the QC one gets sometimes a knife with a significant blade play. I think, if Puma does it (Rc testing) for rather medium quality products, one should do that for the CPM D2 Millie too.
Thanks for your comments.

Tom, I agree, for sure. My somewhat provocative idea of stamping a Rc hardness on blade comes from the lack of any Spyderco's catalog info about Rc. Some time ago, Sal decided not to put any info about Rc value. IMO, not a good decision - sounds as Spyderco steels are soft and ELU should not know that. On the contrary, Spyderco steels are among the best, and Sal almost always answers a question about a particular Rc values. So, why to hide a Rc number?
Chris Reeve, for example, signs for every Sebenza a document with Rc number included.

Once again, we get into the fact that the average Spyderco is not the same price as the average Sebanza.

Hi Franco,
There is much controversey about Rc and too little actual knowledge about RC so we make them the way we think they should be. We've not had customers complain about hardness. Just the virtual argment about the numbers.
Regarding certs, I believe there is about a $200 price difference between most Spyderco's and a Sebenza. If you would like to send me the extra $200 with each purchase, I'll be happy to personally Rc your blades and give you a signed letter of authenticity.

Off to Tom Krein the ZDP Endura will go! I did some informal cutting and everything goes into small pieces nicely. It is hard to compare it to my other ZDP knives at this point because the other ones are so much thinner, but it seems to be holding it's edge much better than VG-10 at a similar profile, as expected. It will be a treat to use once Mr. Krein hooks it up with a Military style full flat grind with a nice, pointy, tip. Thanks again, Tom.
Also, I should mention that the ZDP Endura is flawless in fit and finish, with zero blade play. The blade seems to perform as you would expect ZDP 189 to, so making a big deal about a 63 RC test reading prior to using the knife probably wasn't warranted, but it did seem a little low compared to the RC values I had heard thrown around with Spyderco's ZDP. If I had never gotten it tested I never would have suspected it might test "soft", so take that for what it's worth. But you know how us knife knuts can be, I just had to know the RC values on my collection!

Ah, now I know why Sebenza is so expensive - it is $200 difference because of certs.
I was wrong thinking it was because of almost custom quality.
Franco
P. S. Sal I really wrote bona fide comments in this thread. I do not believe that measuring Rc value costs additional $200. I even do not ask for Spyderco to do this. I simply would prefer to have 'Rc 61' stamped on my BG-42 CF Millie instead of the childish 'Earth'.
A dimple caused by Rc testing is not unusual in Europe. I remember Aitor Jungle King II also had it .

Hi Franco, I hope you know I was just teasing about the cert?
However, regarding the stamping of Rc, it would add cost that I feel most customers are not willing to pay for. Also Rc is generally listed as a range of +-1. That means any accurate stamping would have to say Rc 59-60, etc.
I question anyone that can say absolutely for sure that their knives and testing are so accurate that each and every knife is 61 and only 61. Just my opinion.
Regarding the "Earth" stamping, Sorry you don't like it.

i dont know much about blade hardness but I still dont think I need an Rc number on my blade. If it works, use it. I definately dont want it if it means added cost.
I dont want my blades stamped like a billboard, Just make it sharp.
As for the "Earth" thing, I think its kinda cool.
Just my opinion, I could be wrong.

I'm fine with this. No need for every blade itself. In fact, in actuallity I'm not too consernd with the RC of my blades, just so as Long as they are above 57, then I'm happy. But seeing the Rc in the catiogle would be helpful for someone like me, as I work in cutlery retail, especailly when I have customers who insist on asking me about, oh say roughly 125 questions per knife, before they'll settle on one. I personally adore spyderco more than any other brand, including almost every custom and limited edt I've ever come accross. But when a customer wants details about Rc and I only have an educated guess on sypercos, and Benchmade has em listed on every knife in their catilog, if that question is asked, its usally and important one, and because of benchmade having listed it, Benchmade tends to sell over spyderco in that case. WHEW!:yawn:
Its sucks for me, cuz in all honesty I think Spyderco is the better knife and knife company all around. I think listing the Rc in the catilogs would be very helpful.
