Hi all,

There is a thread on another forum that discusses a test of CPM-S35VN done by CrimsonTideShooter.

http://www.bladeforums.com/forums/showthread.php/905685-Any-response-to-this-S35VN-Related...

Part of his test included a Spyderco Native5 with CPM-S35VN. Since We don't think it proper to discuss our Native5 on another company forum, I started this thread for discussion here.

We are trying to retrieve the knife in question so we can test it here in our lab. We are also testing some of our Native5 CPM-S35VN models that are on the shelf. Initial testing of Rc showed an average of 59.5. Next week we'll CATRA test models here to see if they're consistent with our earlier S35VN findings. We'll keep you posted.

Sal, I am always impressed by your pro-active involvement with your company. Kudos good sir.

Although for me the CPM-S35VN in the 'other knife' seems to be working great, I'll follow just to see what you find.

Cheers and chapeau!
 
I don't want to take this discussion in the wrong direction, but can you please explain what CATRA is? :)
 
Sal and Eric's dedication to excellence is probably one of the main reasons I will always own and continue to buy Spyderco knives. Thank you guys at Spyderco, great work as always!
 
Sal,

Its dedication like this that truly impresses me. Thanks so much for listening to your customers and always bringing the best performing steels to the market. I have enjoyed your knives for many years and will continue to do so for years to come.

mine is. i've not done any intense testing as i don't really have time to spend on this but in my daily uses that range from cadboard to food prep to game processing ... no problem. not the best steel out there obviously but in the S30V range, not better, quite different.
 
Great to hear, Sal. The commitment that you and your company have to quality, testing, and improvement is a major reason that I'll continue to buy and use Spydercos. :thumbup:

Testing Method

The principle of the test is simple. The blade is mounted in a position with the edge vertical and a pack of specially developed synthetic paper is lowered on to it. By oscillating the blade back and forth the blade cuts into the paper, the depth of the cut being the measurement of sharpness. The test media is loaded with 5% silica, which has a mild wearing effect on the blade edge. By repeating the back and forth motion, the further cuts are made, which wears the cutting edge. The measurement of cut depth at each subsequent stroke can then be plotted to produce a wear curve for each blade tested. The test produces two indications:

- ICP (Initial Cutting Performance) representing the cutting ability (sharpness) of the blade as supplied
- TCC (Total Card Cut) which represents the life of the blade by giving a measure of its total cutting ability

My Native5 blade tested at 59.46 HRC.

I performed manila rope cutting and compared the performance to that of a Buck Vantage Pro with its Paul Bos heat treated S30V blade at 59.69 HRC. I was unable to discern any difference in performance.

I did not notice either chipping or rolling of the blade. Since my test method is based on inspection of the blade under magnification, IMO I would have seen it had it been there.

I couldn't have said it better
 
Hi Crimson,

You can email me at sglesser@spyderco.com. Telephone 800-525-7770 My assistant's (Olive) extention is 208, although I can be hard to catch by phone, a time can be set. You can also leave a number and I can try to reach you.

Hi Knarfeng,

We Rc'd the Natives on the shelf and 59.5 was the average, though none were off of that by much. Our machines were recently calibrated, which we do regularly. We'll test with CATRA on Monday. We'll also have some independent testing done.

The issue with testing is consistency and sufficient sampling to avoid anomolies. Cutting rope is ok, but difficult to find consistent rope as standards of rope mfg are loose. We cut rope and insulation back inthe 90's. When CATRA developed their latest machne, we bought one as they seemed to have solved many of the consistency issues. We test regularly and we've tested many thousands of knives.

This is the first "complaint" we've heard of forf our S35VN knives, but our production with this steel has not been as much as with S30V (which we still use quite a bit). We'd like to determine what happened with Crimson's test, as I'm sure many others would as well. My personal Native5 has been used quite a bit, with no negative indications, but I haven't been cutting anything tougher than a lot of cardboard.

While it's next to impossible for someone like Crimson to do, testing 5or 10 knives of each model and maker would be better, counting cuts, etc. The fact that the same results happened with just 2 knives makes it hard to come to conslusions.

Mr. Glesser,

If I recall correctly, Mr. Ankerson did rather extensive testing of S35VN in the recent past. I no longer have the link, but since he's very active on your corporate forum, perhaps you could benefit from contacting him, and reveiwing his "real world" experience. :thumbup:

From extensive personal research , I have come to greatly respect his opinions and conclusions based on his test results. :)
 
Just out of curiosity, will you be testing S35VN knives other than the Native? Personally, I have a preorder for one of the sprint run Paramilitary 2's that are coming out with S35VN blades and would love to know how those hold up. Thanks.
 
Jim told me he could not tell the difference between the performance of S35VN and S30V either.
