As someone who uses Darrin's heat treat service, I would be interested to see how one of my blades with Darrin's heat treat would hold up, if I thought that I would get useful information on how to improve my own designs and quality, or Darrin's heat treat for that matter. But, I don't drink the Noss Kool-aid. I've never seen one of his tests that makes me feel like the guy understands anything about knives. All he does is abuse them. Doesn't take a knife expert to wear a mask and beat on a knife with a sledge hammer. Nor does that advance the art. I'd love the opportunity to figure out how to improve my craft and make a better knife, and I wouldn't be sad to see one of my blades come out second best against a company like Busse or Swamp Rat (even though their vaunted SR101 is just 52100), provided that I could learn something from the experience. I don't see what can be learned from abusing a blade though. I shoot for designs that will perform cutting tasks as efficiently and comfortably as possible. I learn something new from every design I've made, and I've got many years of learning ahead of me. I don't design knives to stand up to being stuck in a vise and beat on with a sledge hammer, nor do I design them to chop through concrete blocks. If I want to pulverize a concrete block, I would take it on with a jackhammer, not a knife, and it would give me no comfort to know that my knife COULD do that, since I feel a responsible knife owner should, and would, treat their knives with respect.

Truth be told, I would be far more proud to make a knife that a custom maker would be glad to own, than to make one that Noss would give a good report to. That is, I value the opinion of experts in the trade, not the opinion of abusers in a mask. YMMV. As for commanding a great price, well, it takes a lot of work to make a good blade. I haven't even brushed the surface of the level of skill of some of my favorite makers, since I'm just a hobbyist who's getting started. But I would be pretty unhappy to see one of my blades go to someone like Noss who, in my opinion, won't respect it. Maybe that opinion will change if I ever do this for the money. But for me, every knife I make is a learning experience. I don't see any evidence that Noss knows enough about knife design, heat treats, etc, for me to value his opinion. If Jerry Fisk ever started doing destruction tests (fat chance, IMO), then I'd love to send him a blade for his perusal. Kind of a sad statement on our times that people denigrate custom makers who actually know a lot about making knives, and tout the "work" of a guy in a hockey mask who's never made a blade himself (AFAIK).
 
Well, if you sacrifice everything to get toughness yes, but I don't think that's what Scrapyard does...

...If you can do THAT tough and keep up with every other aspect of performance, then you should send a knife over to Noss and encourage him to race it against a Busse or at least a Swamprat; the PR from a win would be amazing. That sort of toughness isn't relevant to everything, of course - I've never needed - but a custom maker who beat Busse in Noss's test would be able to charge an awful lot for one of his knives.
Dan Busse of Scrapyard knives states that his knives are designed purely for function, and in many cases that function is pure "toughness". But recent offering have included the ScrapMax series (340, 375, 460) which are designed for cutting efficiency and might survive only as far as the Mora Clipper in Noss' demonstrations. This would not be unexpected.
Noss' demonstration of the RAT/ESEE-4 increased their sales, I bet he increased sales of the Mora Clipper and BRKT BooneII as well, but hurt sales of the BRKT Bravo 1. Why would his demonstrations affect sales of these different knives in any way? Customer expectations. What do you, as a customer, expect your knife to do? If you care about how it performs in Noss' demonstrations, fine. But those demonstrations only inform on the limits of what one aspect of a knife is capable of. They aren't Ankerson's tests and don't pretend to be. They also favor very specific designs. Dan Keffeler, custom knife maker, submitted a blade for one of Noss' final demonstrations (he no longer does these destruction tests) - the blade was a monster, and it easily survived everything thrown at it (better than Busse)... but if you look at the design, it may appeal to very few customers, and yes it is expensive.

As someone who uses Darrin's heat treat service, I would be interested to see how one of my blades with Darrin's heat treat would hold up, if I thought that I would get useful information on how to improve my own designs and quality, or Darrin's heat treat for that matter. ...

Your ad hominem comments about Noss are silly (you admittedly don't know anything about the guy, nor does he know you) so I've excised them in the quote above. What matters is that you don't design your knives with such limit-testing in mind, you're not designing toward that aspect. :thumbup: Then OF COURSE the information gleaned from such a test would be of minimal use to you. Any kindergartener could tell you that. But certain Bussekin knives ARE designed with such extreme use in mind (and an important note, it's not the task that is inappropriate, it's the tool, and just because your tool is inappropriate doesn't mean that everyone else's is as well - different knives can achieve different goals, this does not make one less of a knife than the other). SR101 is 52100 treated to a specific end - if you desired the same end, you would seek to imitate or improve upon that specific performance, would you not? Look how stout some of those "tough" knives are - is there any question that they were designed for hard use? If yours are not, why bad-mouth someone else's design if it accomplishes the function intended in the design? :confused: And then bad-mouth someone who voluntarily produces free data on a knife? What sacred law has the man violated? Whom has he pissed on that you piss on him so?

Let's try for a little bit of mature objectivity, shall we?

Darrin Sanders has made the OP an excellent offer. If the OP likes the looks of his previous work, will he jump on this great opportunity?? I, for one, hope that he does. Get what you want, how you want it, unique and high quality from a reputable maker, and bless that maker with a sale. :thumbup::thumbup: Who loses? :)

What sacred law has the man violated? Whom has he pissed on that you piss on him so?

I don't recall bad-mouthing any designs, nor bad-mouthing Noss in particular, beyond pointing out certain points that are probably verifiable, one way or another. Perhaps you should read the argument before weighing in on it?

I'll break it down for you.

Main Assertions that I take to be true:

1. I don't believe that Noss has ever presented any evidence that he's any kind of expert on knives, nor that he has ever made any himself. I tend to think it's verifiably true that none of the "tests" that he does are scientific in nature (nor does he make any claims to such, IIRC), and also do not demonstrate any clear knowledge about knives. It doesn't take a knife expert to bash a knife with a sledge hammer, or to baton through a concrete block, or pretty much anything else that he does. I think that's verifiable, because anyone, from the mall ninja to the well-respected maker or collector, could do the same things that he does. If you disagree, and you believe he's somehow an expert on knives, please do share why you think so. I would be interested to hear your evidence and analysis thereof.

2. I don't believe that Noss has ever made a knife. Again, something that, if I should be wrong, should be fairly easy for one of the Noss crowd to disprove. Show me a blade that he forged, ground, and heat treated himself.

3. I do not believe that a skilled knifemaker has anything to learn from someone who has never demonstrated any expertise in the art of knifemaking. I submit that the burden of proof rests on you for an assertion of that sort. I'd much rather trust someone who has demonstrated expertise in the craft than someone whose only expertise seems to be breaking knives. Creation is always harder than destruction.

And 4. I don't believe that meanwhile owns a blade that's been heat treated by darrin.

Things that are verifiably true:

1. I use Darrin Sanders heat treat service.
2. I own a RatManDu.

So here's the crux of my argument.

My theory of making is that if I'm going to make a blade, or offer one for testing, that I'd like to learn something from it that will allow me to advance my skill in design and crafting. Based on the above, I don't believe that Noss offers a maker, even one as novice as myself, the kind of information that would make it worth my while to have him test my designs or Darrin's heat treat. If I were going to have a destruction test done, I'd want it done by someone like Jerry Fisk, who is considered a National Living Treasure in the field of knifemaking. He could doubtless provide me with all kinds of useful information that would help me improve my own skill.

I have no doubt that there are many people who think that Noss provides a valuable and important service. But from my perspective as a hobbyist maker, there's nothing beyond hype to be gained from having Noss test a knife, and I'd rather learn something, and have my work respected, than have it destroyed to satisfy the oft-ignorant crowds on youtube. When you've spent hundreds of hours constructing a custom knife by hand, is it so strange that you might want it to go to a loving home, rather than a place where it gets abused?

So I tend to take issue with comments from people like meanwhile, who, likely without so much as owning a piece of Darrin's work, make a comment that implies that he, and every other custom maker out there, cannot possibly compete with a production company like Scrapyard or Swamp Rat in terms of making a knife that's both tough, and still performs.
 
Crimson your not alone in your didain of Noss's tests.

I'm wondering how a custom from M4 would perform alongside Swamprat's Sr101/52100.
 
crimsonfalcon07,

You don't sound very smart. I think you are the one who needs to learn about knives. Also you don't understand destruction tests. People like you with little minds usually don't. I can tell people things about knives that many people can't because I do what I do. You say makers don't value what I do, Well call Jerry Busse and ask him about it. He gave me the FFBM to test. He understands and does destruction tests all the time on his knives. This is one of the main reasons he makes a bad ass product. He knows what his knives can do, he knows the limits. D-testing was no doubt a major influence when he developed INFI. A few other makers have donated knives also and I have turned down knives from makers because I am retired for now. Also if a knife does well in my tests they sell a lot of knives for makers. I had almost 6 million views on my old noss4 YouTube account. That's a lot of potential buyers. I got to a point I no longer had to buy them to test anymore. So you don't know jack about what I do other than I wear a mask. Big deal. When I start testing again I will be sure to wear it just for you and I will mention it also during the video. Also no, I don't make knives I have no interest in it. I never did. I don't need to make them to do the tests. No reviewer or tester does.

It seems reasonable that many folks would truly appreciate your testing. It also seems reasonable that many folks would not appreciate your testing based on the extreme handling of the knives. Both types of folks would be justified in their thoughts about this and it is easy to argue in favor of each side.

Your post above, however, discredits you entirely. Name calling and threatening childish and spiteful behavior on video is counterproductive to reinforcing your value to the knife community. In some small way, having knife makers names in the same post as this rubs some of that discredit onto them as well.

Just my .02.
 

Aha, the man himself comes to respond. I find it telling that he confirms all of the things I had taken to be true. Particularly the point that he doesn't think he needs to make the knives at all to do the test. That just makes my point for me.

Bear in mind, I'm not saying that the tests are worthless to everyone. Obviously there are many people who appreciate the information. But, not surprisingly, Noss, like his fans, misses the point. The point is that because he doesn't have expertise in knife-MAKING, only knife-BREAKING, there's only a limited amount of information that a MAKER can glean from his tests if they want to improve their craft, and that only comes from a single "test" in an uncontrolled environment. [edited out more tangential response]

-edit- Also, my apologies to the OP for derailing his thread. I only meant to say that he should take the unsubstantiated assertions that folks like Darrin cannot make a knife that's as tough as one from Scrapyard or Swamprat, etc, with a serious grain of salt, and to make up his own mind about whether or not destruction tests are important to him. I personally have found Darrin's heat treat to be great, and while the RatManDu is a good choice (I have one), I have yet to see it outperform the BK2 or even some of my own blades, to any noticeable margin, since I draw the line at hard use, rather than outright abuse. If anyone wants to take the Noss line of discussion further, I suggest we take it to its own thread.

Mr. Noss I have never watched one of your videos because I've never heard of you until now but I'll be looking for you on the tube. If you ever decide to start testing knives again please contact me so I can get a knife to you for testing. I have always wondered how my knives would do against a Busse. I'm not saying one of my knives would outperform one and I'm not saying it wouldn't. I honestly don't know because I have only seen one Busse that I made a sheath for. It would be cool to find out though.
 
Okay, first, gentlemen, please extend the respect to each other that many of us have for each of you.

I have a very nice blade made by CrimsonFalcon and heat treated by Darrin, and it's AWESOME.I am eagerly watching his growth as a knifemaker. I can understand his perspective as a maker.

Noss, your reviews have had a huge influence on the way i think of knives, and what they are capable of. Were it not for you, I don't know that I would have ever considered buying a Busse knife ( i now own one, and have 3 more on order) , and i greatly appreciate your work.

CF, i don't know that Noss has much to do with makers... i think his tests are much more focused on the user. I for one found them to be incredibly valuable. From the perspective of a maker, i can see why the tests would be doing most of you no favors, but understand that Noss NEVER makes any claim that he is out to teach people to make better knives. He never claims that his process is a scientific comparison, rather he picks up a knife, shows it to you, then runs it through a battery of tests until it breaks... then he shows how, and where it broke.

It's not science, it's USE... very nasty, and in MOST cases utterly unnecessary use, but it gives a very clear picture to those of us who are looking for that kind of knife, which ones can handle insane, stupid, destructive abuse, and continue to function. This is valuable simply because it is unique. No one else has done this to the extent that Noss has.
 
Since I seem to have started derailing another thread, I'm moving my comments to this thread, and people can feel free to respond here, so as not to take up space in the other thread, which isn't about Noss.

My initial comment, in response to this post:

Well, if you sacrifice everything to get toughness yes, but I don't think that's what Scrapyard does. There's a nice example here of their sibling brand Busse's "Skinny Ash" taking on a Fallkniven A2 and beating it on just about every aspect of performance:

http://knifetest.com/forum/showthread.php?t=455

If you can do THAT tough and keep up with every other aspect of performance, then you should send a knife over to Noss and encourage him to race it against a Busse or at least a Swamprat; the PR from a win would be amazing. That sort of toughness isn't relevant to everything, of course - I've never needed - but a custom maker who beat Busse in Noss's test would be able to charge an awful lot for one of his knives.

Very cool that Darrin says he's up for it, if Noss wants to un-retire.

My initial post engendered some confusion and disagreement (probably not surprising), so here's the breakdown:

Main Assertions that I take to be true:

1. I don't believe that Noss has ever presented any evidence that he's any kind of expert on knives, nor that he has ever made any himself. I tend to think it's verifiably true that none of the "tests" that he does are scientific in nature (nor does he make any claims to such, IIRC), and also do not demonstrate any clear knowledge about knives.

And 4. I don't believe that meanwhile owns a blade that's been heat treated by darrin.

Yikes! Rather than responding to the points I made, he went ahead and made it personal, and confirmed that he doesn't know anything about knifemaking. Okay then.

And then this cogent point was made:

I don't think the guys at Car and Driver make the cars they test, either.

And to that I say, that point is likely very true. However, the guys at Car and Driver have credentials which demonstrate a fair amount of expertise about cars, and how they're made, etc, which I don't personally think is equaled in any of Noss's videos, nor has Noss made any claims to expertise about the craft. His videos are fun to watch, for some of the same reasons I watch UFC, but I don't see them as being particularly educational experiences from the standpoint of someone who wants to learn more about knifemaking.

The main thing that I think gets offered by Noss's videos, outside of entertainment value, is a sense for what kind of abuse a knife can take before it fails. Some people find this valuable. I'm not sure I'm one of them, because I come from the philosophy that one should use their tool for its intended purpose, and treat it with respect (especially because taking a knife to the point where it breaks can be dangerous for the end-user). But YMMV, and that's fine. To each his own. However, I'm not sure how effective these "tests" are at helping a knifemaker improve, however, because of the limited and unscientific nature of the tests, and what I take to be the lack of expertise from the videos.

What I'd like to see is some cogent and reasoned responses from those of you who value Noss' work, and hopefully you can help me understand what can be learned, in context of improving one's work, from his videos.

And in particular, I would like to see some response to this assertion: "I feel that destruction tests can be useful, but that they are BEST done by someone who understands the craft of making knives, since that person could provide valuable advice on how to improve. They also should be controlled and repeatable tests, so the value of the data can be easily collated and understood."

Here's what I'd envision being ideal:

Have particular categories for what we take to be important. Control variables as much as possible to test those categories in a repeatable way. For instance, If we think that side-to-side flexing is important, do the same test they do in the ABS so we can measure the exact angle it can be bent to before it gets damaged (although the ABS recognizes that's not a good idea for every knife). If we think that edge holding whilst chopping through a concrete block is important, we should probably do two sets of controlled tests, one for the knife's natural POI, and another for the portion of the blade that's off. We should also see if we can control the angle of impact, to limit variables as much as possible, and have measurements of the edge grind angles and geometry. So on and so forth.

The tests would also be useful if we had specific metallurgical and heat treat measurements, so we can assess how the heat treat affected the overall performance.

Etc...

Then, have someone who knows what they're talking about go through the tests and provide analysis. Isn't that what a good review is supposed to do anyways?

Certainly, props to Noss for starting the whole d-test fad. But it can, and should be done better, in my opinion, and his videos are repeatable by pretty much anyone who has a lot of money to waste, and a willingness to destroy a knife for the entertainment of others. There's no particular expertise required, and the educational value is very limited, as things stand, in my opinion. Feel free to disagree, but do explain why, so that "little-minded" people like myself can follow along. Perhaps use small words?
 
Quoted from the previous thread

I have a very nice blade made by CrimsonFalcon and heat treated by Darrin, and it's AWESOME.I am eagerly watching his growth as a knifemaker. I can understand his perspective as a maker.

Noss, your reviews have had a huge influence on the way i think of knives, and what they are capable of. Were it not for you, I don't know that I would have ever considered buying a Busse knife ( i now own one, and have 3 more on order) , and i greatly appreciate your work.

This is valuable simply because it is unique. No one else has done this to the extent that Noss has.

I would say that a person experienced in USING knives is better suited to provide end user feedback than a person who makes them, just as I trust the opinion of a person who owns a knife that i am considering more than that of the producer

Made a new thread so as to not derail this one further. Perhaps we can take this debate there, and return to recommending good knives for the OP? And for the record, I don't disagree with anything that you say, Chris. I do think his videos are geared towards the user, and that he's been clear about that, and that's fine. My thought was to present an alternate perspective so that people don't drink the kool-aid whole hog, and recognize the limited nature and value of the tests. And that's the extent of what I'll say in this thread.

Back to recommending things to the OP:

Fiddleback Forge has some really cool things that might interest you. Bark River has great knives, but I don't know that they quite have a reputation for durability. If you're looking for a production knife that's "built like a tank" at an affordable price, ESEE, Becker, Condor, and of course the Swamprat and Scrapyard knives that have already been mentioned, will likely serve you well. But if you can have a great custom knife made for you at comparable prices, and you get to specify the design, intended use, steel type, etc, I'd consider it strongly in your position.

Let's say, for the sake or argument, that I decide to video myself testing knives by frying eggs on them. Stupid, utterly unnecessary, insane even. But unique!

So that would be valuable?
 
I think that you can learn some things from destruction tests, but only if done in an escalating manner. Take them first through fairly basic tasks. Then start upping the level of abuse until reaching a point of failure. This lets you know the "window of manageable stress" of the knife and can give the end user a better understanding of what the knife can or cannot do without damage. It's the threshold point that I consider most valuable knowing, and that tends not to be addressed in most destruction tests. They are usually done in a "look at how badly I can mangle it before it finally snaps!" manner rather than a "let's find the very most it's able to take without damage" one.
 
No disagreement here. I think you're right to say that Noss is geared towards the user, not the maker, and that he does provide what's currently a unique perspective. I do think it's unique because nobody else really wants to go destroy knives, and I think that's probably telling. But consider, if we think that destruction tests are useful, why not really do them well? Why NOT make them scientific. Why NOT give makers something to aspire to, and to improve on? There are clearly companies that are happy to cater to the folks who want big and tough (zero tolerance, for instance), and if they get a destruction test video that not only tells you how and where a knife broke, but also goes into depth on the physics and metallurgy behind the failure, or at least provides data with controlled variables (say, use a power hammer so that the impacts are at a precise angle, force, and in the same spot, etc), imagine the kinds of knives you'd get!

Noss has never made any claims to be scientific, that's true. But wouldn't it be better if the tests WERE scientific, and if Noss could provide cogent analysis about the design flaws, the metallurgy, the edge geometry, etc? I would think both the maker and the user would benefit from that kind of information. Noss deserves credit for opening the field, but for the same reasons he himself has stated, his videos aren't the be-all and end-all that so many seem to think. I can't tell you how many times I've seen people say that a Scrapyard or Swamp Rat or Busse knife is somehow superior to a knife made by some other custom maker because of Noss's tests, often without that other knife having undergone similar testing, and with no thought given at all to what that custom knife was designed for, or to the level of artistry involved in making it.

to someone who wants their knife to be able to fry an egg, absolutely.

I would say that scientific testing would clearly be preferable, but currently no one has been willing to take on the expense of putting together the necessary scientific equipment and doing such testing. Since Noss is the only one doing it, i'll take his tests until someone does it better.

engineering and physics would improve his tests, yes, but the lack does not invalidate them

I can sort of see the value in destruction tests, because there are so many irresponsible knife users out there who think they can abuse their knives, and then complain to the manufacturer when it breaks. I think it's probably BAD to cater to that sort of person, since I think we should encourage them to become RESPONSIBLE knife users, and NOT abuse their blades, but making tougher knives that can still accomplish the same tasks isn't a bad thing, and DOES advance knifemaking. It's the attitude that so many d-test lovers espouse that I find sad and problematic, as well as the unthinking adherence to a blade because it did well in Noss's tests. If you recognize that they're unscientific and valuable mainly for their unique nature, why place so much stock in them?

It will be a sad, sad day when people start valuing their knives for their ability to fry an egg, etc. Just sayin'...
 
Just for my own gratification, I like to know the failure point of any tool I use, if possible. Plus I love to see thing destroyed.
