52100 at 66rc, Edge Stability versus Toughness with Thin Geometry

Geometry plays the role for durability vs cutting ability but its always fun to do some destructive testing to see what happens.

[@CliffStamp]

Rob Simonich used to do nail cutting to promote his knives/steels (Paul Bos HT). Whenever anyone did anything like that I was always curious as to what it meant/said about the knife/steel. I would just duplicate it and see what happened. With the nail cutting after doing about a thousand cuts, I determined it was so sensitive to technique I would never be able to infer anything from watching/or knowing someone else did it. I could barely know anything myself. At the end I could take knives which were 0.010"/15 dps in D2 at 62 HRC and cut through 4" nails with them with careful technique. It was mainly about keeping the knife extremely close to perpendicular, making sure the nail wasn't moving around, and just tapping it through. I figure I could (maybe) put some kind of metric on it by restricting the number of hits, but the influence of technique was still so demanding. I could easily damage an AUS-8 blade at 58/59 HRC over the D2 if I was just a bit sloppy. In general toughness tests are demanding for the user because they are so sensitive to conditions which can easy vary enough to make a change far bigger than the steel. About the simplest setup I can think which would be decent would be if you just swung a knife (through a pendulum) under a given energy (weight/height) and impacted it against hard targets. That's fairly easy to set up and quantify, and it similar to a charpy test of sorts.

[@FearNoSteel]

Thanks for sharing Cliff. Larrin did an article on Frank Richtig which was interesting, he hammered through bars of mild steel with fairly thin knives and the secret (technique) he was using for his demonstrations died with him. Larrin is the one who has the device you speak off. It was a rather expensive device but very interesting. I'm not promoting a universal nail test. I am a caveman that needed a quick test that was destructive enough to show differences between some variables in the same knife that the lay person can contextualize.

Got a small fixed blade with Aeb-l at 63hrc and around 0.010 for most of it except the tip. I haven't chopped through nails but I did shave on one and the edge acted like it was nothing. I'd love to get a river blade from you, just wouldn't know which steel to choose. VanCron 40?!?!

[@hobbyman47]

52100 in 66hrc sounds like a good sujihiki or yanagiba made in that steel with same heat treat and hardness.👌🏾👍

[@CliffStamp]

As an aside, that knife showed brittle failure, that just means when it fails, it does so with little (to no) plastic deformation. A knife can have an extreme high UTS point, and still be brittle, it is in the nature of the failure, not the level of resistance to it. It does look like it has high apex stability as it retained a high sharpness while doing work which is likely to roll or cause carbide related fractures at the apex, but I would want to see a comparison in something like ATS-34 at 63/65 HRC, or 10V at 65/67 HRC to be confident, as if they don't fail either, the test itself might not be generating enough stress.

[@FearNoSteel]

Fair enough, not shown, not known. In my experience the 52100 with proper HT is less prone to chipping at the edge than a carbide blasted steel but that's not to say 52100 is superior for all circumstances. I enjoy the merits that 52100 offers but I am more partial to steels like 15v that simply cut longer without blunting smoothly with heavy cutting.

[@CliffStamp]

@@FearNoSteel Yes, I like it for almost the same reasons, and AEB-L (and similar nitrogen steels) in stainless as they have similar behavior.

[@FearNoSteel]

@@CliffStamp that nitrobe 77 you told me to try was very very interesting, the wear resistance was low but it was very impressive to sharpen and very nice with thin geometry. Labor intensive HT though.

[@CliffStamp]

@@FearNoSteel Yeah, it is very demanding to ensure no retained austenite in high nitrogen steels assuming you want max hardness as nitrogen is a strong austenite stabilizer. I am not sure these steels have functionality outside of extreme corrosion, as you can get 63-65 HRC in AEBL, depending on how fancy you want to get (see Landes for example who water quenches after tempering, etc.).

[@FearNoSteel]

The water quench between tempers is not as significant a factor for Increasing HRC on AEBL as much as the time and temps used during Aus and temper and doing immediate cryo after quench. In my testing, there were no changes to HRC when doing a second cryo in-between tempers or water quench after tempers, however, there may be benefits to the microstructure that is beyond what the Rockwell tester can show, perhaps shifts preference for more desirable constituents in the microstructure that may give increases in YS but not UTS at the edge.

Many look at your vids and think that you made a magical blade as they watch you cut through nails, not realizing that your a pro user.

[@FearNoSteel]

it's still 52100 at 66rc with a badass microstructure. I could "pro user" all day but if it was shit, it would be shit.

[@ASOKAEdge]

@@FearNoSteel true. No knock on your heat treat prowess. Followed you long enough to know you continue to push the limits to achieve maximum performance. Keep it up

[@mikafoxx2717]

Yep. Japanese blades are run hard and high carbon, and very thin, maximising edge retention and cutting efficiency. Most knives are still pretty thick compared to what they could do. Edge stability is king. You can go for higher hardness or higher toughness but you need a good ratio between them for edge stability. High toughness in a soft steel is just ductile, and high hardness without toughness is just brittle. A hard 5160 would be a great chopper and better than soft 1095.

[@rustytygart405]

[@antonkudris]

Thanks for taking your time to shoot and upload this video. I'm not sure I understood you well, cause around 1m mark you noted that 52100 doesn't have the most agressive edge, nor does it set any records in terms of edge retention. Then you talk and demonstrate so called 'edge stability'. The differences between edge retention and edge stability are pretty elusive to me. Knife's edge looses cutting ability when it receives too many micro ships or edge rolling (lets just call it edge damage). The ability to withstanding micro edge damage is what I think 'edge retention' is. And thus in my eyes 'edge stability' is pretty much the same thing. Is it the place where I mistake? If I'm not mistaken, then it's unclear why would you bring steel to such a hardness if it doesn't bring better edge retention (you said about edge retention around 1m mark) Please pardon my English, I'm not a native speaker.

[@FearNoSteel]

knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/

[@FearNoSteel]

Harder with stable microstructure means better support for thinner geometry, I demonstrated that the 52100 could be thin and hard with the right microstructure and still stable on the blackwood. The Carbides are one of the most significant factors to edge aggression and wear resistance. While the steel is harder at 66rc it won't be more wear resistant than s90v at 60rc despite the higher hardness of 52100. Why? Well there is some good reading in the link I sent.

[@antonkudris]

@@FearNoSteel yeah I've read that blog. Can't say I understand everything, but still. I'm not really interested in direct comparison between 52100 and other steels. But I wondered why you pushed 52100 to such hardness. In my understanding the only reason to cook steel such hard is to get better edge retention (compared to the same steel at softer hardness) Let me rephrase my question. Imagine you heat treated two pieces of steel, one at 66hrc, other at let say 62. How much of a difference there will be in normal use? I had a nice collection of high end kitchen knives from modern knife makers. There were 2 knives one at 65hrc. To be honest I haven't noticed much difference between then and knives at 61-62hrc.

[@FearNoSteel]

@@antonkudris read the first part of the answer I gave you above again, because if you go thinner and the structure is not stronger it will roll over in normal use while cutting without having the support of thicker geometry. So if thinner geometry cuts better but needs more support it needs to be stronger. The Carbides control wear resistance and they don't really change with HT like they do with the steel chemistry. It's pretty straight forward.

[@macmurfy2jka]

I’ve always said it, people don’t give this “spring” steels enough “knife” cred. There’s a reason Collins uses it on their high end axes. Toughness makes any impact tool better, full stop. I wish we saw more “hard use” knives use it so they could maintain better cutting geometry while still remaining hard use. Especially considering how cheap the stuff is.

[@FearNoSteel]

It would still need to be thicker geometry to support the steel so it doesn't roll in use. Also it would wear smooth easy in cutting tasks comparatively and be more stubborn to deburr and apex if heat treated for maximum impact toughness. There is no fairly tale steel, they all have trade-offs just like everything in the real world, nothing wrong with getting something that suits your preferences my man. It's fun to have something rough and tough though.

[@macmurfy2jka]

Big Brown Bear oh, don’t get me wrong, I understand that, everything is a ballencing act it steels. I’m talking using this steel over other really simple steels in things like machetes or “survival” knives. I can’t imagine it would be too much more expensive. And if it makes them more abuse resistance at a similar given hardness or the same toughness at higher hardness or allows for a thinner edge I’m not sure what the real down shot really is. Please correct me if I’m wrong.

[@FearNoSteel]

@@macmurfy2jka I don't understand, you mean 52100 at 66rc for a machete/survival knife? I don't think that would be cost effective to heat treat and grind for production margins.

[@macmurfy2jka]

Big Brown Bear nah that would be silly. I’m assuming you took this up to a really high hardness and then tempered the stresses for a long time? No I’m just interested using this steel over something like 1075 or 1095, and bringing the hardness closer to say 60 with somewhat better cutting geometry, then letting the steel’s mechanical properties provide a margin of safety for use. My guess is that doing this would produce better users at a price that still allows them to be semi disposable, like any good user should be. I mean, to my knowledge, that’s how allot of the “good” tools seem to be made in 3rd world backwaters (using truck springs). It just seems like an under developed section of the knife market. Mid range knives that make better users. I might be missing something, as all of this is from a bird’s eye view. Studied materials properties and manufacturing techniques in a few classes in college, but most of my user experience comes in the forms of simpler HighCarbon steels. Never could afford big pieces of M4, O1, etc. I don’t have any personal experience with the steel as so few makers use it and I’ve never ground any of it into a knife personally. Is it just too hard heat treat? Performance gains not economical/ margins too slim? I just think that the steel is largely overlooked.

[@rickodonnell2243]

I only have ceramics water stones how much of a mess would this be to sharpen on a chosara 800?

[@FearNoSteel]

Rick, it's not the hardness of the overall Matrix that determines that, its the carbides. MC3 Cr rich iron Carbides at ~ 6% volume and ~1200 HV is not going to interfere with the Ceramic abrasive grains at ~1600 HV which are harder, it's when we get Vanadium Carbides(~2800hv) at Significant volume and high matrix hardness that prevents the abrasive grains from cutting around them as easy making it a total goat fuck to use ceramic for that.

52100 does not have comparable toughness to 5160. 5160 is a lot tougher.

For swords? No idea, I make knives. I would think the advantage of higher wear resistance is lost on a sword and that dropping the carbides like 5160 does is probably better for what a sword does, I have no interest in swords however.

[@AaronJohnson1979]

Maybe a dumb question here,, it took me about four years just to confidently get to the point of making a good knife. Now I want to start pushing simple steels i use to the limit, trying to get the most from them. Is there any different kind of bevel or honing/buffing you can put on a super thin hard knife edge like that with that same geometry, That can help it handle that nail chop. But still not lose much cutting performance?

[@FearNoSteel]

Ya should respect that geometry and hardness, those features are counteractive to chopping a nail at such an extreme, I showed this in the video when I was able to chop the nail with thicker geometry

[@FearNoSteel]

You have to remember that when I share a video like this I'm pulling back the curtain on the inner workings of what makes things work. That opens me up to a lot of criticism from folks that think they could do things better.

Two things thin knives can't cut is time and cost. It rewards skilled users, and holds ppl accountable. Reckless users, who refuse to see not only what they cut, or what's behind what they cut wont enjoy the experience very long. Ceramic tile, concerete walls, various metals etc are going to be the enemy. I carry production knives as convenience. I cut frequently over a tile floor so mishaps aren't noticeable given my skill set. When I'm cutting drywall I'm using a utility knife. Just makes common sense to use replaceable blades when I'm cutting stuff like that. And since I own a lazer of yours, I prefer it in the kitchen over a cutting board. Cut about 10 apples a week with it. BD1N is never going to be a hot Rod steel but as a user I'm controlling the environment so edge damage is avoided. This vids about 52100 tho. Custom heat treated 52100 to be accurate. Just a solid, high enjoyable steel that gets overlooked.
