Re: DLC and rust.

If you take the DLC by itself only, yes, you are correct. But thanks to surface tension, oil will infiltrate and bond to do sides of those "pinholes", cracks or any other microscopic imperfections, sealing them (of course, not forever, the oil can be displaced with other materials, react chemically...

Re: DLC and rust.

It is better to have no coating than to have a coating with imperfections, at least in terms of structural failure. A good paint layer will protect carbon steel, but a paint layer with pinhole imperfections can actually lead to premature failure of the substrate (for example a chemical tank with coa...

Re: Knifejoy Exclusive Para Military 2

Seeing how 20CP is simply an analog of Crucible CPM S90V, and we have lots of S90V sprints. 'Spect it's cheaper to buy Crucibles version? It's 20CV. No. We are referring to 20CP, not 20CV. Spyderco used to make sprints in 20CV and it was awesome. This was about a decade ago. In my experience it out...

Re: K390 PM2 | Testing

They followed Hitachi's recommended hear treat for the clad Hap 40, and Crucible's for Rex 45, and the results were different. From page 6 of the CPM Rex 45 Edge Performance thread "HAP 40 is heat treated in Japan. They have their own heat treat methods due to the laminate. REX is made by Crucible i...

Re: More 4V anyone?

What exactly would 4V give me that is enough improvement over M4 and Rex 45 (both of which I have) to justify buying it? For folder use improved toughness is not a determining factor for me, as the others I mentioned are fine in that regard.

Re: Military 2. What exactly is going on?

No, that is just over a year of hard use and how the picture turned out. You can tell by the blade size it's been sharpened probably over 100 times. Scrubbing and magic eraser will make it slightly more purple, but it's certainly much darker than a new one. Sharpened over 100 times in a year due to...

That's why I added "depends on the work environment".

Re: Going against the grain

When their eyes glaze over and pupils dilate, you know they're thinking "serial killer?" or "militant survivalist?" Lol. I guess my (sorta) against the grain is a lack of concern for edge retention. And trust me, I understand how holding an edge might be very important in various situations, I just...

Re: CPM M4 vs K390

Shawn, you clearly like K390. How would you compare 10V to it? Edge strength, edge it takes, edge it holds, all else being equal in terms of good heat treat and geometry.

I live in the USA but 1,326 miles from Spyderco. I would spend a lot to save on a few knives.

Re: Unpopular Blade Steels That You Like?

Back in the day (70s-80s) Puma used a basic stainless (1.4110, more or less similar to 440B) that they hot forged and heat treated well. It was easy to get sharp, and held an edge better than the 440C available (Buck). I once tested it against Benchmade 440C on cardboard, and it lasted about 10% lon...

Re: October and Rex45

I carried this one on a seven day backpacking trip the week before last (AT through the Smokies end to end). It was strenuous and plenty sweaty. It got a few pepper marks on the blade, which would likely have been worse if I had not wiped it down with Vaseline before the trip.

I think Knifeworks should definitely run their green/204p combo in the Para 3 as well. That would be an instant sell out.
I agree.

How About a Para 3 in CTS-20CP and Gray G-10?

Count me in if it is ever done. This was the configuration of one of the earliest (first?) PM2 sprints, which I have.
