Strongest folding knife !

There are different environments. Some wet, muddy, dry, cold, hot, dusty, sandy. That said..... Stainless steel, FRN and ballistic nylon are a good start.

I live by the ocean as well and I can watch carbon steels rust literally on a humid day. I only make a few carbon steel damascus knives at a time and keep them coated in Paraffin wax until sold. I really prefer CPM-154, 440C and a few other S/S.
 
Thanks for the infos guys. Always hard to find proper info on the web and figure out what is true and what isn't.
 
The edge on stainless steels lasts much longer than said edge on a comparable carbon steel. There is some much BS and misleading info on the net and about knives still around it sad.

What are you talking about?!? By the way, I've got some blades I just forged up and I don't mean to brag, but I can pack an edge like no one else;):D



...there is indeed tons of misinformation.


To FFK, a really strong folder is still a folder. The design does look interesting though. Would like to see some video of testing and a more detailed look at the folder itself (once you get a little further along).

So you are one of those edge packers?:D That's going to compress steel on a atomic level with a hammer! Yeah, right! LOL.
 
Yep it's a folder. Will streamline/thin design a little bit, use G10 for handles. No rush.....it takes what it takes.
 
That's my brother. Another spider man.^
FFK- I like your folder idea. Do it up.
rolf
 
It's still open so I can scroll down and my mild curiosity turns to horror when he opens his mouth.
 
I read about stainless not getting as sharp as carbon on various sites. Supposedly the grain is finer? I admit I have 't done any real testing, just going theoretically here.

First link I found googling here: http://lansky.com/index.php/blog/the-secrets-of-steel-part-2-high-carbon-steel/

While a little OT, I don't think this writeup is really very fair. I am a huge fan of high carbon/tool steels, but an equal fan of stainless steels. I feel certain applications make one a better choice over the other depending upon the usage it will see.

I think it's almost impossible to approximate all high-carbon steels to all stainless steels as a whole given different tool steels and different stainless steels have different characteristics depending upon the steel, and further the same steel differs (sometimes greatly) depending upon the heat treatment.

Additionally, the article doesn't seem to acknowledge that chromium is only one of many elements going into stainless steels, and that these elements dramatically impact the properties of that specific steel. Alloys allow one to (more or less) tweak a base so that they can create a steel that is matched for an application, and it is why there are so many different steels on the market given they are being made to fulfill certain roles. While a stainless steel may be defined by chromium content, that doesn't really mean a whole lot just on its own in assessing a steel, IMHO. For example, high vanadium content in a steel is generally associated with pronounced wear resistance as vanadium carbides are exceptionally hard (for example, CPM-S110V stainless steel).

I was also a little surprised to see the generalizations about toughness givenhe neglected to note that a stainless steel such as CPM-154 is actually tougher than many of the carbon steels he listed by a considerable margin and he compared CPM-3V to CPM-M4 in toughness and wear resistance, yet these steels really have very different properties.

The other thing that surprised me was that he has grouped steels into the "CPM Series of Steels". At least as far as I know, that signifies a patented PM (Powder Metallurgy) process owned by Crucible. As it relates to how the steel is actually being made and not what steel is being made, it is used on a variety of different steels: some stainless, some not.
 
Why is this thread still open?


Because the OP, myself and many others are exchanging information and while the OP may have started off on the wrong foot he has come around, bought a membership and has continued to be teachable to the standards of transparency and forthright speech we strive for here at BF's.

I don't see why this thread should be closed? Do you have a reason?
 
OP is a "knifemaker" with a non-knifemaker membership spamming the bejesus out of the thread with his brilliant idea.

Maybe I just read everything wrong?
 
You were doing great until that last line.
Not only can you make a stainless steel just as sharp as a equivalent content carbon steel, The stainless edge will outlast the carbon steel.

Don't mean to sidetrack the thread, but I've heard that carbon steel is easier to get scary sharp than stainless. Is that correct?

Also, good job op. Without people like you all knives would still be fixed blades. You just have fight through all the negativity first.

The OP has stated he has no knives for sale.
I think this is a borderline case, but he is here to talk about knives, rather than sell, at this stage.
 
I think "carbon steel" is being used in an ill defined manner. Some use it to mean Iron+ carbon, nothing else. Others think it means non stainless.

The guy has nothing to sell (at this point), just sharing a prototype.

Should everyone that post up a knife they've designed/made/pimped/etc. have to buy a 'knifemakers' membership level when they currently aren't selling anything?

Some of you guys got your pitch forks and torches in hand and are just looking for a witch. The guy already bought a gold membership and he's just sharing his concept. I'm sure he'll buy the appropriate membership when he plans to start selling (and if not, it can be dealt with then).

Yes,
Carbon steels like say, 1095 & O1 are easier to sharpen to sharpen than stainless steels, like 440C or CPM-154 because the Chromium & other elements add an abrasive resistance. Keep in mind that the other side of the coin then comes into play with carbon steel's. they won't hold the edge as long as stainless.

In knife lingo there is a number of Appox 13% chromium or more in the mix for us to call it a stainless steel. That number may not hold in other steel applications.

The semantics of what to call what can be challenging. We are talking about these commonly used culinary steels,
Correct?

These steels have .50% or higher of carbon and are what can be defined as Martinisic or hardenable, correct?

Well, so far our new pal Mike seems to be more of a designer and hasn't offered up one knife for sale yet and as stated has done the right thing after a few corrections.

I think we should show a little more of a warm welcome and let him develop as a new gold member that has some good thoughts and ideas about cutlery that he can contribute to BF's.
