[@uguuwuu6882]

Hi Dude It's a list of the more common/well known steels in the video (as well as the ones associated with well-known brands of friction folders), so that most of the people who stumble onto the video but aren't interested in watching the whole hour will likely be able to pick out the steels they're interested in without having to click around for a while to find them Edit: I've never actually had a comment of mine pinned by a youtuber before, it's a nice feeling

As a child of the early 80'S----that corny intro made me almost laugh out loud.....good on you. On a serious note, thank's for all the effort you put into your tests. As a knife guy who actually uses his tool's, it is appreciated. Greetings from KY.

I just found your channel and have been binge watching while wrapping presents. I’m a subscriber now, but after this video I’m a LOYAL viewer! I’m one of those guys who “eats this shit up,” but I also love your honest presentation. The internet is full of BS and attitude, but guys like you and a select few others make me glad to still pipe the internet into my home. Keep up the great job, and I’ll be catching up on older vids while you heal your shoulder.

[@samthai818]

4 years later and this compilation of tests is fucking awesome! thanks alot Cedric! (pete) Ignore the idiots doing their own tests and getting different results. They completely change your methodology and then want to argue the result. complete idiocy.

Great video! Brings back memories of all this lol, but now a video with all the tests....its like gold. I just got another Steel Will Modus in m390 for only 100$ on amazon and did my own test with 3/8" sisal and praise the Lord I got 450 cuts....so I didn't get a lemon. Phew.

[@herbertgearing1702]

On behalf of knife nerds everywhere thank you for all the work that you do to entertain us. Try to take it easy, I have personally experienced some aches and pains from chronic sharpening, whittling, and fidgeting. But more importantly try not to let negative comments from internet trolls bother you. There are people with no friends and no lives who use the internet to lash out in an attempt to spread misery. You can't reason with them, you can't negotiate with them. You will need to learn to ignore them for your own piece of mind. As a great man once said, "f*** them, they ain't us!"

Brilliant work Pete! Your contribution to the knife community is immense and highly appreciated! You've personally influenced me alot as edge retention is something I'm very interested in! Watched the whole vid in one sitting and was absorbed, have referred to your Google sheets data but having it summarised on video form was really helpful! Really enjoyed it and looking forward to your review of the Spyderco Advocate :p

[@jameshewettjr.3147]

Great, great effort documenting steel performance in your own way. Does give a regular user of cutting tools a fair perspective. Thanks for your effort and seriously take care of that shoulder.

[@danielbottner7700]

Appreciate all the testing & insights you derived from your testing methods. Testing should mirror your real world use case scenarios for sure. Developing the testing methods, tools/test rigs to reduce variables & collect data is not easy. Simulating real world use is key to relevant results. Your testing provides us insight into the relative cutting edge stability. I appreciate your sincerity & honesty.

[@kd6tas]

This is good. I appreciate what you're doing. I get tired of reviews that lack anything close to objective data concerning the actual performance of the knives. Further, your testing has answered a question I've been wondering about for a long time. Thermal treatment of cutlery steel is a big variable and undoubtedly an expensive process. Your testing suggests that the blades on all but the very worst knives undergo at least basic thermal treatment. How well it is done can vary, but at least an effort is being put forth in all but the worst cases. Let's say the steel comes normalized and the manufacturer uses stamping and/or material removal to make their blades. There is no forging or thermal treatment. That would save a lot of money on equipment, supplies and time. The manufacturer can claim whatever they want with regard to the steel used and the process it underwent. End users who do nothing more than slice paper and shave hair off of their arms won't know the difference. I suspect that's what counterfeiters count on.

[@tphvictims5101]

The beginning video is hilarious. I learned quite a bit from your site. Brought new life to my lansky diamond kit. I gotta get that stand attachment. I guess I should I’ve had it close to 40 years.

[@an-mf9ib]

The "Cedric and Ada Steel Comparison Ratings"-excel sheet is great! Cheers! Reviewed it so many times already. Ive been hoping someone wouldve just put those steels in order for years now and have some comments on the process as well. Good stuff! Hopefully I can find all the steel there soon(ish?). Many interesting still missing. Also some videos on the toughness testing too. For fixed blades thats usually more important than edge holding. Thanks again!

[@M240Bravo]

Got me some coffee, bunch of knives, sharpening kit, Wireless headphones... ready to watch the hell out of this

[@icandi9178]

Great work! Been watching your stuff for years. Invaluable asset to the blade community! Very comprehensive using the same grind (workshop 20 degrees), same cut media and same cut test. I think you mentioned this in the past but the blade digging on the cutting board may be a factor. Here is an idea: if you double up the rope and cut it in the air then you don't have the blade hitting the board. But this means your test will take 5x longer. I can't imagine cutting like that for 300+ cuts... Okay never mind :) Big thanks again!

[@IamNemoN01]

My experience is that Cru-Wear is tougher than 3V, but not as stainless as 3V. My two Cru-Wear knives are ALWAYS developing rust; whereas my two 3V knives never seem to get rusty. And I’ve had my BRK Grizzly the longest. That said, even though it rusts quicker, I would still preorder a Bushcrafter if they did a run in Cru-Wear. The thing I like about the Cru-Wear is that it hardly ever needs to be sharpened. I exclusively used a Cru-Wear Aurora all last year for bushcrafting, and I only needed to sharpening it ONCE. And I did a lot of batoning, feathersticking, cutting rope, and other tasks. I’ll be putting my BRK 3V Bushcrafter to the test all this year. And so far, as I said, it doesn’t rust like the Cru-Wear. I have a CPM20CV Mini Canadian in the mail right now. That will be my primary EDC for a while. And I’m hoping BRK will do at least one final run of the Featherweight Hunter in Elmax. A little birdie told me that they have some of the steel already cut for another run. We just need more people to show an interest in the Featherweight Hunter so Mike of Bark River will be motivated to push it into production.

[@MONKEY-vi7hx]

Thats alot of work! Deserves a thumb up.

[@JustIn-op6oy]

I put an 18 dps mirror polished edge on a nicely ground acuto+ ripple that's been holding up as well as my 154cm grip. For whatever reason, the sharpening process was very satisfying.

[@ssunfish]

It didn't seem like an hour long video. It is a facet: your results. Steel choice, quality of making it, quality of hardening it. There's so much that can go right or to the wrong...even the grind and sharpening affects how the knife will perform. Some want sharpenability and lower cost, but that maybe cause that's the offerrings from their favorite company. I was surprised the ranges...from 8 cuts on "stainless" to 1400 cuts on Rex 121. Plus getting a wide range just on VG-10. Supposing it's possible and applicable for some businesses to spend the money on the hardening instead of the steel. How bout spending on both and save on handles? That's what's happening on my Delica 4 wharncliffe in HAP-40. THANK YOU! I got more on HAP-40 from you in this video by accident than when I went LOOKING for info on it!! Love my Spyderco even more now!! I badlt want a PM 2 in Rex steel but can't land one. I think I'll be covered with my sole HAP-40 and my PM2 in 20CV. I want to get involved in making my own knives to get features addressed that knifemakers and production knives cannot do bec their knives have to have a bare minimum toughness and durability. Your video sparked SO much wonder here! I am not searching for an ultimate steel, knife, design or edge holding. But from your video I feel there's a lot of possibilites for a great knife which can meet and exceed my needs and wants!

[@dougbulldog9947]

[@JoeyB7615]

Thank you for this ..I appreciate your intent that you put into this as well

[@progunliberal]

So, I have a bunch of budget knives in 8cr13mov and I will say, it's so damn easy to sharpen them with a worksharp Feild sharpener. It's very satisfying to hand run a Kershaw through the process a few times and come out shaving hairs like nothing. I know it doesn't hold long, but for my use (mostly box cutting and such) it's a lot of fun to get an 8cr back up to razor sharp with minimal effort. I will say, however, my mini grip is s30vn hasn't needed to be sharpened yet, and I've used it through several trucks of product at work already.

[@jasonh1767]

Howdy from the Republic of Texas! I'm a new subscriber. I don't recall for certain, but I believe it may have been Metal Complex, Beez Blades, or Stassa23 who recommended you. Maybe it was all three. Anyway I'm thoroughly enjoying your videos - Please keep making them.

[@brandonfranklin8979]

i know its an old video but I'm pretty new to your channel. I've become a steel nerd over the past couple years as my knife buying/collecting has picked back up after a pretty long hiatus. I gotta say that I love your stuff man. I love that you have a set of parameters that's followed for each test that makes the results more... I don't know more quantifiable, or more tangible I guess. Anyways, thanks for putting out what you do and for putting your arm through all of the hell that you do from these tests. Cheers!!

[@Spectt84]

Thanks for the hours and hours of effort put into this testing. This testing is as good as one could hope for without a lab full of expensive equipment and a fleet of scientists. I genuinely appreciate the information here. It would be interesting to see someone (with a bit more math skills then I have) figure out an average "CPD" or "cuts per dollar" to help us find the best bang for the buck. Or at least a few underrated steels that perform better than the price implies it should. Anyway thanks again for all your work.

[@nicholassosin6965]

[@c62west]

Thanks mate. Great video. Newly interested in knife steels and this has been really useful.

[@ssunfish]

CTS-XHP...was reading last night it is not so tough or edge holding but your info was that its great for fixed blade! I might mis-remember but you said it was a version of D-2 in powder metallurgy that had more ingredients to make what features D2 has happen better...as in more reliably. That's what I took away.

[@nitrorc4life1]

[@kingtaj]

Hey Pete - could you comment on the ease of sharpening for S110V. You have it rated as a 5, the same as S30V, but I've always heard it's far harder to sharpen. I'm just curious about your opinion on ease of sharpening. Thanks!

[@CedricAda]

yeah these ratings were something I probably need to either retcon or at least redo. S110 is a little longer to sharpen than s30v

[@ssunfish]

Do you have instructional videos? Bec I watched all this and several of your videos and knife lab. I wanted to learn how to apply a toothy edge with landsky diamond. Im most intetested in improving factory edges with slicey angles on dendritic 440C. Thank you!

[@lionknives3]

He pete. I know its a older Vid but please make Spydercos Bdi1 on the manix2 lightweight compare to gerber.

[@oldmateadz]

I've only used a few steels (S30v, 154CM, VG10, 420HC, 1095cv, Cru-Wear, VGMAX, M4) and the champs are Cru-Wear and M4! Very keen to get a Rex45.

[@79istp]

This is excellent! Is there a way to test resistance to chipping? I'm hesitant to err towards very hard blades/edge retention (or even intentionally sharpening steeper), as I seem to be more likely to break them than run out of edge, either from sharpening too steep or batoning.

[@SuperSteelSteve]

So is this your thesis for KZbin University? Lol

[@WallStreet749]

Wish you would make a downloadable PDF for the steel states.

[@romanshvydkoy8589]

Would you do a test on Nieto AN58? This is not very well explored steel, and I wonder how it holds against other similar steels, which I'd assume to be of 440C level.

[@matthirn7858]

Thanks for putting all the work into such an extensive steel review. I like the fact that you are noticing the varying performance or Chinese D2 and even calling out suspect steel like in the Y-Start.

[@SCQT]

[@anthonyp7051]

Dam! That’s covering a ton of cuts,,,thx for keeping this going. There’s deff a enough to pick up from your ch that’s been helping me understand how knife steel works and how the market works.

[@zironemegeaz]

Shoulder injury for science, much respect Sir!

[@ayrplanes]

As an engineer, I wish the data were represented as hardness divided by difficulty of sharpening. A hard knife is fine but if it takes ages to sharpen, I find myself deferring sharpening past the point where it should occur. Too soft and you are sharpening constantly. To hard and it takes forever to sharpen. There is some sweet spot in the middle. The ideal steel would be easy to sharpen yet have extreme edge holding. You can't find that by focusing to Rockwell C numbers.

[@Abbbb225]

I mentioned in another comment that I'd like to see some more comparisons of the same steel in different knives, and now I see you've already done quite a bit of that. I still think it would be nice to account for edge geometry by comparing the same knives in different steels, as well as the the same knife in different grinds. Spyderco mules and sprints in various models (PM2's, Endura's, Delicas, etc.) would be a good source, as would Bark River (just do bravo's in every steel - maybe DLT or someone will sponsor you). LT Wright would be good for testing different grinds (like a flat vs scandi genesis). I'm curious how the convex compares to scandi to flat.

[@richardhenry1969]

Don't know how I missed this one but Pete thanks for putting the work in. Now when I fight with someone I have data points other then fanboy feelings. I've always been a buy a knife to use guy, not a pocket jewelry type. An you have helped my theory about buying expensive knives I just don't get on that ban wagon I'll neve own a chris Reeves can have something that I'm afraid to lose if you know what I mean even more the paying for a 20 yearold design that's production anyway that another story thanks for your work an no job is worth hurting yourself exercise is always the answer

[@nathenwallis5664]

I would like to see ZT's CPM20CV tested when you can get around to it.

[@ssunfish]

Are you considering the ZT with Green coloured Carbon Fibre designed by Emerson? I have not seen a lot about it as far as reviews. I may skip that offerring.

[@JustIn-op6oy]

The muela is probably 440a. Just came across an older coffee table book 9n European/Asian pocket knives and the Muela entries are all some form of 440.

I miss the BK17. It was a thinner, more sensible becker. I can only find one left on eBay for about €150. Is the BK7 a good alternative? Its longer, thicker but quite tall grind. Wish Becker had a lighter, more normal hunting/utility option.

So has ATS34 completely fallen out of favor? My Gerber "Michael L. Walker Design" seems like a pretty good knife. ATS34 was pretty popular about 15-20 years ago.

[@techwg]

I thought the higher the number of the angle, the more hard wearing it is. How some some of your really shallow angles like 12 degrees are cutting for longer than 20 degrees?

[@CedricAda]

I can only speculate, but I think its cos they are harder to ‘flatten’ over, as long as they arent so steep it they fold or really fail dramatically. But yeah, its fairly consistent in my results thr super steep, super sharp edges go better

[@andergraph1]

Awesome testing. Thank you very much.

[@FenderFingers72]

That intro. Classic and hilarious.

[@kevola5739]

Repeatability in you tests will verify your accuracy. If you randomly retest a few steels and get similar results allowing for variables then you can feel confident that the majority of testing done is accurate. This can set a baseline for steels and create a plus/minus tolerance of what can be expected. Or you can fire up the BBQ and while the shrimp are grilling go play with the kids and dogs. Then test your arms recovery by seeing how many arm curls you can do with a cold brew.
