    While I hear you, at the end of the day, it's cheaper to do exactly as you describe. Furthermore, I think it would shock and disgust you to find out exactly how many companies across a countless number of industries do this exact thing. It's simply cheaper, and again, if your product fails, they can just replace it with one that doesn't. And again, we're talking about pocket knives. Where are all the people who are using M390 bladed knives and oh gee, if only it'd been four points harder, it wouldn't have broken, or gotten dull? Does anyone have an objective metric on how long between sharpening an extra four points gets you?

    I mean, objectively I know the answer is "No, no I don't, because there are simply too many variables to correctly ascertain what you're asking for", but I wanted to give you the benefit of the doubt.

    Yeah but you've presented that kind of like a sort of dichotomy, either they're "in the know" or they're not. It really is a spectrum, so they're aiming for "people that know but don't really know" which is to say they know M390 is a hot steel, that it's "the best", but they don't know the science behind it, the effect of heat treatment, geometry to match the chemistry etc.. They're aiming for the people right in the middle with these knives, right at the big fat meaty part of the distribution. $$$$$$

    It's probably more reliable but it's resale value isn't going to skyrocket the way a Rolex will.

    I don't have a Rolex but I do have a Timex. Over ten years that cheap quatrz watch has kept on ticking accurately without even a battery change. Meanwhile my more expensive watches like TAG go to the service center regularly for changes, pressure checks, new o-rings, new batteries and the last time the guy said he's surprised it's still working as well as it does.

    Both watches were bought to tell time. The less expensive one for where if you bang the crystal on your nice watch you'll be unhappy. Kinda like knives, common sense says the less expensive one gets used when the chance of damage is higher.

    Like knives there are watches out there that maybe aren't as good as others. It feels like some of these new companies that are trying to shove their way in for a place at a crowed table by offering a hot super steel at way less that other brands are the equal to a Rolex from a table at night market in Hong Kong. It might look good for an IG pocket dump. I'm sure not going to feel sorry for anyone who believed the hype and is now feeling ripped off.

    HRC is one important parameter... but actual steel composition is another
    How do you know that your s35vn knife is actual s35vn ?

    Thing is, It's not difficult to obtain that range of hardness. Mistakes can and do happen I'm sure, but it would actually cost more (probably less than a penny per blade though) to draw back the hardness to say, 56-57HRC. It's a higher temp and/or a longer soak in the oven.
    It doesn't really make any sense to lie about it and risk your reputation over a few points on the Rockwell scale.

    This thread shows the rabbit hole we go down when you begin questioning the honesty and practices of the companies. We start with companies having bad results on HRC and now we are questioning their steel. I know some companies have been caught with having wrong steel but at what point are honest mistakes and mix ups being treated as malicious intent?

    When brkt lies to a customer and tells them that 20cv should patina after 10 minutes. Turns out it wasn't 20cv.

    But I get your point. This is indeed a rabbit hole.

    There are absolutely bad apples but lets not spoil the hole bunch on a few. You also have issues like BM and their soft 3V, I think it was 3V, that they said was soft to make it easier to field sharpen and make it "tougher"/more chip resistant. We all know that they were running 3V too soft but they landed it in their listed range so while stupid they were honest and that is what we should want from the companies. We want a listed range and we want them in that range if we take issue with that range then we can simply not buy. I still would expect companies to on occasion have one leave the factory that isn't in the range. I wouldn't expect to see a 52 when target range is 58+ that is probably a bad batch that got through w/o any testing.

    I’m honestly surprised there seems to be pushback on the idea I put forth (or demanded, depending on how you look at it)

    A lot of the rebuttals seem more rooted in skepticism than anything else, though, saying the test results would be of little value due to batch variability / potential dishonesty.

    I don’t know much about the details of heat treatments, but, isn’t it a process that can be made into just a rote and mechanical sequence? Temperature, duration, etc - If all the blades are roughly identical, and the process is routine, I wouldn’t expect there to be significant variability between or within batches. Perhaps my ignorance is showing here.

    This is like saying some people drink and drive so all cars should have a breathalyzer ignition lockout standard.

    Secondly; assuming something is simple on the basis that you "don't know much about the details" is going to lead to problems.

    You're vastly oversimplifying a relatively complicated process. Go look into the heat treat threads about target hardness in some of the shop talk subforums. They can have issues hitting a target Hrc on a single blade with a small oven where hot or cold spots are less likely to be an issue. Now imagine magnifying those issues by a batch of several hundred blades. That's the whole reason that when companies do offer information on Hrc they give a range.

    I guess I'm wondering if this is that big of a problem? Would it be worth the extra cost? I joked earlier about testing every knife, but if we truly care about this, shouldn't you want the knife in your pocket to be tested? Where does it end?

    I know more about the board than my join date will tell you.

    Well said. Process tolerance and accuracy are things that have to be considered.

    If a consumer is paying a premium for a blade steel because of the stated properties - typically, wear resistance - then it is a big deal if the company cannot reliably produce blades that fall within spec.

    I don’t think testing each blade would be necessary, but I honestly wouldn’t object. Batch testing would suffice and would also drastically reduce the potential loss of sales due to people finding out they are getting poorly-treated blades.

    I’ll answer the cost question with a hypothetical situation question: Imagine you are deciding between two knives that are equally desirable to you, and have the same premium steel.

    One brand claims a range of 58-62 and costs $240, and the other brand charges $250 and states they have their knives independently tested and have verification that their knife is 61HRC. Assuming you will certainly buy one of them with intent on using it frequently, which do you buy?

    Aitor, a Spanish company used to -not sure if they still do this- test all their blades, and even advertised it. I would not mind knives that showed a test dimple which shows that they where tested, and within HRC specs.
