JacksonKnives here’s Crucible’s explanation of toughness. “Toughness, as considered for tooling materials, is the relative resistance of a material to breakage, chipping or cracking under impact or stress. Toughness may be thought of as the opposite of brittleness.”
@JacksonKnives5 жыл бұрын
@@michaelchristy4982 That sounds reasonable, but shouldn't the definition line up with a measurable property that's relevant to the task at hand? Charpy tests measuring absorbed energy work very well for things like bolts where elongation is desirable, but what does it really mean for an edge in one steel to better "resist breakage" than another steel? Is a catastrophic roll really better than a chip if you've got three more hours of chopping to do? Why do we talk about laminated steel and drawn-back spines as beneficial to "toughness" if the edge is where the damage happens anyhow?

I love all of your videos and thank you greatly for taking the time to share with the community. I find you to be honest, diligent, thoughtful and methodical. While other channels entertain with knives, you teach about the fundamentals that real knife nuts obsess over. You don't just give specs waving blades around. This test in particular was a great new branch for your series. BBB really seemed to get things fired up regarding toughness! My constructive criticism is hard to give as I don't much like hearing it personally. Growth isn't easy. And, your video is obviously better than many commenters below or my own. With all that said... I think more regarding thickness behind the edge should have been mentioned. I think you said 30 inclusive, but that's not all the info we need. Also, commenters said the staple needs to be bent over, I agree. It's early in the process and variables can still change before the format of the test is standardized.

ToxicityAssured I don’t know how much those factors would really matter. The testing and prep for this video stretched over weeks. In that time, I tried making things more extreme by hammering through staples until they cut have. The damage for that followed the same pattern and looked the same. (Surprisingly enough.). If I had found a difference hammering the knives through (which I thought I would), I would have included it. As it stood, it would have just been extra that led to nothing. The knives were at 30 inclusive, but that’s the edge angle. The thickness behind the edge is measured on the primary grind, not the edge bevel.

Hi Michael, your "toughness test" was an actual edge stability test at low energy impact. Dont relate it to toughness as such. Steel behaves differently at the very thin sections than gross material (toughness). Forget steels like CPM-V4 or CPM-M4 being tough. I know that people selling products / steels is where the information came from. So its needed to take it accordingly. These steels are tough relative to their class/application. Toughness in short blades is the least important property anyway. Perhaps the thinnest knife behind the edge could behave as a spring and absorb more energy than thicker geometries, despite identical sharpeing angle so results may still not be relevevant. Obviously there are much more variables to control but just with the same geometries and high amount of trials you would already get a good results. Nice video and idea. )

Hey Michael, I admire and got inspired from what you do. You helped me with my M390 PM2 and took my sharpening skills to another level. Thank you again. I wanted to ask you one thing: Have you ever had your hands on CPK (Carothers Performance Knives)? They have fixed blades from 3" up to 12" (even now making 18" sword). Nathan Carother is magician of heat treatment. He mainly works with CPM 3V. And created his protocol which is called Delta protocol, now it is like brand, his 3V is being called D3V. Amazing performer. Here is what Nathan says: "The steel is Crucible CPM 3V at HRC 61-62 with a fully optimized heat treat with very good edge retention and edge stability. You'll be surprised how sharp this gets and how well it holds an edge. If you have never used 3V this hard and thin, it is gonna blow your mind." And "A side effect of this heat treat is a higher percentage of free chromium, so although it is not stainless, it is nearly so." He cuts nails, cuts bolts, cuts cinder blocks with his knives. I would love to see your review about one of his knives. They are usually sold at bladeforums at their subforum and if one cant grab from Nathan (as their 10-20 knives sell in seconds every 10-15 day) there is second hand market where some collectors or regular guy sell them for bit extra price (around 25-50$ extra). I do own their Field Knife 2 5" blade and awaiting for EDC 3" model. Field Knife performse amazing (second hand price is around 300-350$ and EDC is from 250-300$). You will be surprised how easy it is to sharpen (like carbon opinel) but resists abuse and holds edge without any problems. I have had regular 3v knifes, boker folder, coldsteel and other maker knifes but Delta 3V is completely different thing. I think you must try it. I even wrote about my small sharpening experience on their subforum and said that you influenced me a lot. Thanks a lot for everything. I just want you to try and enjoy their D3V it will change your mind about some things lol. And if you have one, I want to see and hear your review about CPK D3V.

Don't know if the photos are to scale, but it looks like the bevel on the M4 knife is taller, as compared to BBB fixed blade, which might be a factor. I think we need to consider stock thickness and thickness behind the edge/bevel height, as well as angle (for a given thickness behind the bevel and bevel angle the bevel height is fixed, i.e. the base and sides of a triangle).
@michaelchristy49824 жыл бұрын
Abe the knives are at different thicknesses behind the edge, which is why the bevel sizes are different. The bevel angles are the same. The different thickness behind the edge would only matter in this kind of testing if the damage was enough that it moved onto the primary grind, which I don’t believe that it did. (Or not very far into the primary grind.)
@Abbbb2254 жыл бұрын
@@michaelchristy4982 I'm not sure about that. I don't know if it's something that has been studied, but I can imagine that the bevel height may play a role. Essentially, it's having a larger or smaller wedge of the same angle. That might affect how vibrations travel/harmonics, and how much compressive load the wedge can take. Having thicker or more massive stock behind the edge may also be a larger reservoir for vibrational energy, or otherwise change how vibrations travel (possibly being weaker for certain harmonics, i.e. if it is less flexible). Perhaps there are some engineers or metallurgists who want to weight in.

Thickness behind the edge will make a major difference as will Rockwell hardness. I have a favorite little fixed blade knife in AEB-L hardened to 62.5 that chipped quite easily in use. Is AEB-L a steel lacking in toughness? No, it was a thinly ground knife with a very acute edge angle. I applaud the attempt here, no matter the flaws. Even when everything is kept constant, your results may still be the same (depending on how thinly ground/sharpened the blades are).
@kogrady24095 жыл бұрын
The BBB custom knives are ground very thin. I'm not sure of the exact behind the edge measurements on these knives but I doubt his 4v custom was any thicker than the knife in M4 and it took less damage. My guess would be that it's actually ground thinner than the folder. I agree that ideally everything would be kept constant thickness wise for more accurate results but I don't think it had much influence on this test.

Could have just been a difference in your sharpening. Arms tire ex. Plus you hold your stones when sharpening which is janky as hell. Try a better set up I would suggest and your results would be more reputable.

Skankhunt 48. What? Here’s an idea. You spend your own time and money, make your own videos documenting everything including sharpening your knives on whatever system you want and post your own results. Then we can all armchair quarterback your results and nitpick what you did or didn’t do.

Toughness over hardness for me any day.

RMFN that’s cool, but do you realize the hardest of the three knives showed the highest toughness?

Just today I happened to watch this video, of a test of a chopper using S90V at 65HRC: kzbin.info/www/bejne/hJqwqatnm6h5eNk I was surprised to find that S90V has quite considerable toughness at "ordinary" tasks.

Not a correct test. You should do much more cuts than 3... about 20 cuts would be good enough to see the real picture.

NSTD what’s that number based on?
@PATISHAH4 жыл бұрын
@@michaelchristy4982 more numbers, more real picture. You did not make only one number right? If you dont want make many rounds, then you should exactly repeat all test conditions, like blade thickness behind the edge\power of movement\speed\angle\blade part spot\orientation of staple\power of staple connection and so on...

NSTD you didn’t answer my question. What’s the number 20 based on? Do you have a legitimate reason for throwing out that number, or did you just pull it out of your ass?
@TheBigToe694 жыл бұрын
NSTD Then why don’t you spend your own time and money on the knives and video and tests. Then you can post your own results and we can all nitpick what you did and didn’t do. You know, like how 20 cuts wasn’t enough and you should have done 50. Or maybe 75 cuts, or better yet 100 cuts. They all were cut the same amount of times. So the results are what they are. Pulling a random number out your butt like 20 isn’t proving anything other than you weren’t happy about the results and your biased opinion towards a specific steel.

Knife people need to stop being such steel queens… my dads Boker is still doing fine, as is his old Case large hunting knife. Yeah, I’ll pay more for different blade steels, but… quit being such queens!!! And stop paying for whatever price they try to throw at us. People pay only what the market will bare… I think we’re getting beat about our heads with grail knives and then them always being unavailable and thus inflating the prices and then they throw other options at us at STEEP PRICES!!!
