Ranking of Steels in Categories based on Edge Retention cutting 5/8" rope

They are saying it's 63.5... ;)

It will be tested however so I will have a number on the one tested.

But I will go with what they are telling me.
So their literature disagrees with what they are telling you. Has it changed, or did you get a one-off?

Don't know about what the web specs are.

It's not a one of, it is however just on that one model only.
 
Interesting. Yeah, like Chiral said they should be putting that in big red letters on their advertising, or maybe they are afraid of some yahoo smashing it into bricks to prove it's brittle or something. :D

Yeah I think that could be a lot of it. :D

Kinda of the understate, over deliver thing like CRK does with their numbers.
 
Being "built like a tank" with a "bank vault" lockup that can handle the job the best for the military and first responder communities, but this isn't the place for that discussion if you disagree. Feel free to open a different thread in general discussion.

So you get to tell off Zidfelts in this thread, but he has to start a separate thread to respond? :rolleyes:
 
Cold Steel Ultimate Hunter update.

It tested at 63.5 HRC. :thumbup:

Thanks Jim
Now, that is good news. Deep cryo. Hooray.
CS is DEFINITELY giving a good run for the money to their competitors.
Spyderco has been said (not by myself, purposely enough) to know how to deal with CTS-XHP.
I wish it was true as it has been demonstrated by CS.
An example or maybe a couple, better three.
Dice, Domino and guess it the last one [emoji57]
My own Dice scored 61. Domino scored 60 and 60.5 the last one.
No comment necessary as obviously sold they've been.

That's just in that one model, the Ultimate Hunter only as I said before.

The rest will be at the normal 60-60.5 range.
 
Peacefully agreed, mate.
Now why not on a even shorter blade with decent thickness as Techno? Just to pick one (way overpriced) model? Or on Dice?

I know the different companies do different things to the steels for various reasons, same with blade grinds.

The production companies have to be careful what they do, especially these days with the latest trend of YT videos so I would think they are playing it safe.

It's smart really I think as most people likely wouldn't be able to tell the difference anyway in normal use.

it's one thing to have the custom makers running the steels hard and thin on expensive knives ($600 and up etc) that people won't be smashing through bricks etc.

It's another to have regular production knives that don't cost all that much. ;)

Not to you mate by any means.
Said that...
Excuse number one: "we want our customers to be able to resharpen their knives. "
A very VERY respected here and beyond knife maker in real field knife usage witnessed that a charged leather strop it is enough after a lot of skinning etc to bring S125V in excess of 64 HRC back to its original sharpness.
Excuse number two. "Allowing for knife abuse avoiding claims".
Well, if you're expecting abuse you don't use S35VN at 55-57 but 3V at 59-60 and you can nearly blow any media capable of being cut/chopped/pierced to Kingdom Come and beyond. With (yes) not that much less stain resistance and more edge retention.
If you knife maker (in the end) heat treat M390/Elmax in the same way you would 440C you quite missed the whole picture. Or just missed the basics of metallurgy.

As far as I'm concerned now, by means of your results, CS has demonstrated clever and competent HTing.
Thus into they rush in my own personal buying list.

At least for that one model. Jim, is there any hint from Cold Steel that that nicely high hardness is an accident, or that they'll bring it down so it's in line with the rest of their product line?

No, it was intentional for that model. :)

Some people need diamonds to sharpen 440C. ;)

How many times have you read people tell other that they need diamonds for A or B steel?

Personally I use Silicon Carbide for everything I sharpen and use it on my strop too.

The production companies have to be careful these days as I said.

I can fully understand reasoning of companies that produce large quantities of knives. Most common complaints I have heard around the fire while hunting about knives:

1. The steel is "stainless" yet there is rust spots
2. It is so hard it cant be sharpened.

There are simple answers to the above though.

1. They misunderstand the term stainless.
2. They do not understand what sharpening is about. No matter the system they use.

Now for us knife nuts, we are willing to learn and be patient. But for the masses and the guy that is not willing to spend $100 on a knife to accompany his $1000 rifle and uses a pull through sharpener then he will not give a hoots toot about HRC of 63.5, how it was obtained or what is the retained austenite or wear resistance. First question is: Is it "stainless" and once they inspect it they want to through it.

I still find it funny that though people will spend hundreds of dollars on knives, yet they do not understand the fundamentals of sharpening and you go to rural areas where they use a file and a river stone they understand the basic fundamentals. Even if you give them a $500 custom, they will sit and sharpen it the same as any machete.
 
Good point. (A bit off topic) I had a "fellow" helping me install some fake grass last year.
So I get out my old 7" Swibo / Wenger Swiss Insulators knife. It was doing a great job for me.
It must have got a bit dull and before I knew it this "fellow" was going to town on my knife
on the top of a concrete block. Still has big scratches on both sides. But was a little sharper when he was finished.
Not a high dollar knife, but an old favorite none the less. LOL LOL
Most folks would hate 63+, and big smart production companies really do know what they are doing. (More so than us)
Just a little food for thought...........

Agreed, but many times they are NOT touching up when it is all that it is needed.

Yet you didn't comment about this part: "Well, if you're expecting abuse you don't use S35VN at 55-57 but 3V at 59-60 and you can nearly blow any media capable of being cut/chopped/pierced to Kingdom Come and beyond. With (yes) not that much less stain resistance and more edge retention.

Should I think that CS is offering that knife at 63.5 on a daredevilling base?

63+ or even 64+ on modern PM steels are NOT a problem even for my 15yrs nephew just barely using Spyd's Sharpmaker rods ;)

Well, going a bit off-topic, at shooting range last Sunday I met a fellow with his friggin' huge 460SW XVR (me using 45ACP) and when I asked what he was planning to do with that I had been answered "Home defense". He had eventually smacked it in his nose at the very first round as he had clearly omitted to consider that weighting barely 65kg with full power rounds would have not properly been considered as a viable option. He reloaded with the very slowest burning gunpowder as well...go figure :D
Morons' mother she always pregnant :D:D:D:D
His and our lucky day it was, as mercifully and wisely enough the director of shooting range allowed him to chamber one round at a time.
