NEW! CPM S45VN Steel Edge Testing and Steel Talk

[@tacticalcenter8658]

It's all about the heat treatment. Don't think of hrc and don't think of softer or harder. Heat treatment is about heating and cooling the steel. And depending on the up and down temperature and what is happening at those Temps for the desired time. If a manufacturer is not developing a heat treatment protocol and just using the basic one on the datasheet, then it won't be optimal for knives. Lucky for makers Larrin has already come up with some profiles for it that some manufacturers may use. While others will never see and will be quite worse in performance. The key here is to not look at hrc. We want to bring out the proper carbides for edge retention, we want fine grain structure and a micro structure idea for edge retention while reducing austenite as much as possible. And tempering for toughness that makes it less brittle. Hrc is really not that important in the grand scheme of things. Cause you can use a different profile to get a different hrc number and get more or less performance.

[@kknives_switzerland]

This!!! 62HRC is actually really "tame" compared to what's possible hardness-wise - it's indeed also very important to have an ideal microstructure. 👌🏻

[@bele28]

Most important is carbide formation and carbide retention when knife is used. You can have a higher hrc knife that does not retain carbides as well when edge is used as a lower hrc one. Carbides should do the cutting. So it's like cooking.. trying to find that perfect balance. I think the most important step was already done by the community.. and that is.. raise awarness of just how important heat treat is. Understanding how a cheap lower grade steel composition can drastically outperform a very pricey steel just because of heat treat is key. Why spend hundreds of dollars on faulty merchendise.. every knife maker should make it of the utter most importance to get the heat treat right. Because you can make a 1000 knives that kick ass.. or a 1000 knives that are trash.. for basically same money invested. Just dial in on the heat treat is my cryout to manufacturers. Don't waste perfectly good blade steel because of lazyness. Don't fraud your customers by advertising m390 and then have that 300$ m390 outperformed by a 15$ 12c27... it's outrageous. WAKE UP

[@kknives_switzerland]

@@bele28 ABSOLUTELY!! I am so glad to find you guys spreading the word 🤛🏻🤛🏻 Indeed, both at high as well as low HRC hardness you can have good (or bad) carbide stability... It all depends on the overall microstructure.

[@bele28]

​@@kknives_switzerland cough cough.. I m in Croatia.. If you get a reheatreat job on maxamet can I send you my native 5 maxamet blade so it gets a piggyback ride to perfection :D

[@kknives_switzerland]

@@bele28 I am still wating for some Maxamet blades to arrive for re heat treating, after those are done, I may have time. But focus is on my own folders for now. Want sum?😄

Nice vid as always. It suddenly struck me that it would be nice to see a microscopic image of the used (post Sisal cutting) edge. I remember that Virtuovice used to do something like that, back in the days. Cheers!

[@spartan8390]

New to your channel. I bought a knife with S35VN; a week later, same knife offered in S45VN at the same price. At first, I was dismayed at the thought that I may have been left behind. Then I had a revelation. Like all new things; it takes time for refinement. The S35VN knife I chose has been in production for many years from a trusted company; so I'm more than satisfied. S45VN is "a new recipe in the kitchen" and will take time to perfect it. So for now, let us all enjoy the famed classic song, "I've Got A Lovely Bunch Of Coconuts" while our perspective knife makers do their refining. Also, I will be subscribing to your channel at this time. That's right! You made it! The other 30k plus subs PALE in comparison to my subscription! But seriously, great work and I look forward to your future videos.

[@mforrest1508]

I’ve been feeling flat with knives lately. Unsubbed from all channels. Deleted Instagram. But still watch your vids 👊🏻. Well done sir

I got a Benchmade Meatcrafter in S45VN and I really like it, even more than I expected to.

Uncle Randy , I'd like to see him do more reviews 👌

[@officialandproper]

Hope you're doing well and healing quickly! I was intrigued with the direction the video was taking before uncle Randy spurred you to action, but am glad to have learned about s45vn too. Edit: I accidentally typed "s35" rather than "s45"... nice - thanks brain!

[@ciderandthorazine]

what a great knife (even independent of steel). i think infusing nitrogen in a carbon-rich steel is interesting. supposedly, particle steels always include a small amount of nitrogen picked up from the atmosphere during the process. i wonder how much of a role that has had, clandestinely, in the superior observed properties of particle steels generally (that and probable presence of carbonitride). i'm glad to see more experimentation with it.

[@brianf9619]

[@tristanphillips8937]

Nah all steels have trade offs from old steels. Every property you change has another property that changes along with the first change. I have a medically alarming knowledge of steels and I can tell you that every steel has a certain property that it’s good at. The only exception to the rule of trade offs is cpm magnacut. It’s like an extremely stainless cpm cru wear with a bit better toughness. Check it out on knife steels nerds it genuinely is a huge change to how we design steels in the future.

[@BuffaloNickel9]

@@tristanphillips8937 interesting comment thank you! you and I are totally different in terms of metallurgy or steel knowledge I have very little so quick question why has no one used Magna cut in their knives yet ? can it even be used in knives? does anyone produce and is it coming in the future ?Spyderco seems to use every Steel in the book including cruwear m390 M4 maxamet 20cv and on and on but have not heard anyone speak of Magna cut also second question,..,.the only property I seem to be most interested in lately is Edge retention the way I test sharpness of my knives is by how it pops the hair off my arm if a blade isn't cutting the hair on my arm with ease then it is not sharp to me and I will not use it most of the time. so considering all I'm interested in is Edge retention what is the absolute top Steel for just that property and not just a working edge but an absolute Razor Edge held the longest

[@tristanphillips8937]

@@BuffaloNickel9 yes! Magnacut was specifically designed for knives. However, it’s such a new steel that it hasn’t really been produced yet. I heard that after the melt of steel is atomized it can sometimes sit around for months or even years before it is pressed into a solid ingot. I’m very anxious to see some production knives in magnacut too but sadly it may take some time. As for the second question, ive found my absolute favorite steel for hair whittling sharpness is k390. (You can get a pm2 in k390 on bentoboxshop) I’ve found that almost no stainless steels have that super fine edge holding capability just because they have excess chromium carbide. Magnacut will almost certainly be an exception to that rule though. A Non stainless high alloy steel will probably suit you very well:) I’ve carried my k390 pm2 for about 18 months now without a spot of rust so it isn’t a huge deal to oil it every now and then if you want that super nice edge. The reason it holds an edge like it does is the almost 10% vanadium content and very little chromium or other elements. (Other high alloy non stainless steels like 10v and maxamet may achieve the same properties but k390 has that little bit of extra toughness)

[@BuffaloNickel9]

[@tristanphillips8937]

@@BuffaloNickel9 yes I saw a few prototypes that came out during bladeshow this year and I am dying to get my hands on one. Like I said though they may not go into production for a while. They made a test melt to see the properties of magnacut, which was then divided to a few custom makers for prototypes. I’m sure they’ve started the production process for magnacut but it’ll take a while for those melts to be ready to be sold.

I wonder if it will cut “half” the amount as s90v

[@robin2821]

Half x N, you mean.

[@tacticalcenter8658]

That really depends on the heat treatment recipe of the s90v in the particular knife being tested. S90v can be poorly heat treated in mass production while still showing 59hrc. It's how the recipe itself does to the composition of the steel inside. When steel is heated all the components of that steel interact at different temperatures for sustained times. If s90v is not done correctly because a manufacturer doesn't want to investigate the best recipe for that composition, it will be abismal. Never trust manufacturers... Most of them do not do that, only few do.
