Hello all,
I'm trying to figre out what the difference in models are? I've used googled image and have not had lucky finding a pic Or thread explaining.
I'm interestd in the size stats of each.
The "EDC" part of the name has me interested as I'm a fan of edc'ing small/ish fixed blades.

I'm new to the brand and want one like yesterday! Lol
Thank you in advance for any insight offered.

EDIT: Steels offered 3v & D2 correct?

This is an overlay illustrating the tweaks from the original

As you can see it's a hair longer, the belly is pushed out towards the tip and the grind comes up a little higher due to tweaking from .135" to .145". The bevel angles and edge geometry are unchanged. Not seen, the scales are being trimmed down a tad to be a little bit thinner. Not much.

Thank you kindly for the pic!
So is the EDC2 not available yet? I' assuming it' the new/updatd version of the original EDC?
I plan on posting in the WTB thread, I just want to clarify the size details So I know exactly what I want.

TY

EDIT: Not much out there but after doing some work, what I found out is that version 1 is a bit smallr in overall length, has a stubbier handle, blade is more of a spear point. Version 2 has more belly on the blade and slimmer handle, a bit longer? Version 2 comes in 3v, while version 1 comes in D2, or 4v?
I'm really interested in how much longer? The one and only pic I found with both knives, I can't really tell, maybe half inch?
I actually prefer the blade shape of version 1. A pointer tip will be more useful for me. Also if it is in fact a bit smaller, that's a plus as well.
If anyone can let me know how much I got right or wrong, I would be very thankful!

You may want to read up on the tech specs as presented by Nathan Carothers:

The original EDC pattern: https://www.bladeforums.com/threads/20-small-d2-edc-knives-micarta-g10-colors.1471209/

EDC-2: https://www.bladeforums.com/threads/friday-sale-twenty-3-edc2.1539221/

In addition to their proprietary D3V heat treated steel, the original EDC was also offered both in D2 (not PSF-27 aka Optimized D2) and also 4V as limited batches only. So far, the EDC-2 has not been offered in any other steel variants. As you may already we aware, the original EDC pattern is now retired but Nathan is still planning on offering more EDC-2s in his to-be-announced upcoming Friday's sales here. Other than getting the EDC-2 directly from the Maker, you can also try the WTB subform or to keep a very keen and fast eye on the WTS thread on this very subform and also the fixed blade on on the main Exchanges. A word to the wise, the Fridays sales pass by extremely fast pace and all 20 units at any given time get pretty much claimed for within 15-20 seconds of the Sale! thread getting posted at 3:00 PM Eastern time!

You can find all about the The Next Sale here by checking Nathan's OP updates: https://www.bladeforums.com/threads/the-next-sale.1405869/
 
Thank you for the info Casinostocks!
I don't own any 4v knives but I do hav several in 3v. From what I hear 4v is not as tough but holds a better edge?
I know heat treat plays a huge part in performance.

No problem. I think it was the Greek Philosopher Plato who had said something along the lines of, "learning is remembering". Case in point, the more I remember to search back for this stuff, the more I also learn :)

Regarding 4V, here is Nathan's OP when he had the original EDC in 4V for sale:

https://www.bladeforums.com/threads/friday-sale-3-edc-cpm-4v.1500316/

And here is the crux of it as it emanated from Mr. Carothers' finger tips:

These are made of a Crucible CPM 4V, an American made version of Uddeholm Vanadis 4 which is the steel that has been supplanting CPM M4 as the king of steels winning cutting competitions. We have done our homework and optimized a heat treat for this material that I feel is probably the best in the industry. Our interest in this material stems from an on going project to produce competition cutters for Bladesports that I hope will win next year's world cutting championship. These 3" EDC are an off-shoot of that R&D. They are CPM 4V at HRC 63-64.

If you're looking for something that is very durable at relatively high hardness with good edge stability, good wear resistance, good corrosion resistance, not too bad to sharpen and an all around great steel, wait for another batch of these in Delta 3V. The EDC is a great knife in 4V, but it's more of a specialty steel for knife nuts.

It is not as tough as 3V, but it's tougher than most steels. It has 5% chrome so it has better corrosion resistance than stuff like O1 or 1095, but it is not at all a "stainless steel", it will rust easily. If you have good tools it's not too bad to sharpen but I wouldn't call it easy to sharpen. What it has is outstanding edge stability, edge durability and wear resistance that adds up to a level of real world edge retention in normal use that will probably rival anything most people have ever tried. They're hard and thin, but you don't need to baby them, they're built for hard work. And with the optimized heat treat they're not at all chippy or crumbly so they'll take a thin narrow edge and hold it in rough use that will blow your mind.

You da' man Casinostocks!!
Exactly the info I've been looking for! Sounds like Nathan has the heads up on the heat treating of 4v & 3v.
A well HT lesser steel may in fact out perform a poor HT superior steel (of course within reason, not a 440a vs M390 or the like, lol). But when your dealing with such a superior super steel/s AND have a top notch HT process, well then your way ahead of the pack!

I'm really interested to see what could possibly be out there in the future to compete with the above said steels? Knife stuff.... Gotta love it!!
 
Has Nathan ever posted anything describing the difference between his 3V and his 4V?
 
The only comparison in that post seems to be that 4V is more of a specialty steel but not as tough as 3V.

Has anyone compared the two EDCs as made by Nathan? Chop for chop and slice for slice?

I'm not sure if I can post a YouTube link, so I will pass on that. However if you use the search button on there and type in the following (cpm 3v cold steel pendleton hunter) you will find a video comparing 3v and 4v.
I feel confident in saying that the consensus is, 4v will hold an edge longer (can'not say how much longer?) though it is not as tough and would show a bit more edge chipping/damage if subjected to an identical test as 3v. As Nathan said in an earlier thread, 4v would be the love child between M4 and 3v. Edge holding almost as good as M4 and toughness almost as good as 3v. Sounds like a bad A** winning combo to me!
 
^ it isn't as tough, but no, it doesn't show more chipping/damaged compared to 3V. Not generally. This is the reason it's used in cutting competitions, because points are deducted for edge damage and you will be disqualified from a cut if there is significant damage. 4V (and V4E, the sister steel) shows less damage than anything else tested. <--- this is only true with an optimized heat treat, if anyone has tested the material but it had the HT developed for tool and die applications (the industry standard) they didn't get a good look at its abilities. Fortunately for everyone the HT developed by Peter's and used in competitions is really quite good.

4V and V4E will outperform the best M4 or 3V in edge retention, and ability to show very little damage in rough use. The primary down side is failure is sudden and catastrophic. I've broken quite a bit of it in cuts that 3V just took a big dent.
 
Great info Nathan, thank you for chiming in!
It sounds like a toss up in what steel would best suit your needs. For me 4v and it's extra edge holding are preferred. Although I know it' no slouch in the toughness department either.
Either way, both good steels to have in your CPK EDC knives!

Interesting points Nathan. The ht that peters uses for 4v, is it their standard ht or a specialized one you worked with them on to develop like the 3v protocol?
 
although the edge holding on my 4V edc is well beyond what I'm used to with most of the many blades I've dealt with in regards to edge holding, D3V is very, very close. In my opinion, D3V is just right for the EDC, since the slight improvement in edge holding that 4V has is outweighed by its enthusiasm for corrosion, and the EDC is designed to be a 'set it and forget it' type knife where you don't have to do much of anything to maintain it- either cleaning or resharpening

The HT that Peter's uses for 4V and V4E is a HT they worked out themselves. I also worked out my own HT for 4V. When it was all done and we compared notes they were doing something very similar to what I was. We use my protocol for 4V and V4E because in my testing it did what I wanted a little better, but both processes are similar and work well. Neither of them are remotely the same as the HT on the Crucible data sheet, they are not the "industry standard" HT. They are demonstrably better in a thin cutting application with significantly less chipping and edge fragility.
