Dude I freaking LOVE these videos!!! You really excel at these types of teaching videos, E! Your background as an educator is so apparent!! I feel like I'm being lectured by my gorgeous Italian professor about metals in a coffee shop in Naples!! "It's a book about metals"... No one under 40 got that!!! ('Heat', Michael Mann, 1995)!!! Speaking of movies, E, today the win goes to your increasingly incredible background shots in your videos!!! You think you're Stanley Kubrick or something?!?!? You tryna be a cinematographer or something?!?!?! WOW!! Dude, your videos look so incredible cause you have a really good eye for photography etc. Loved this one!!! Thanks so much for doing it!!!

I'm just starting to get into some of the better steels. I now have a few in S35VN and they seem to do really good for me. I must admit I am not a hard user, mostly cardboard and stuff like that. Thanks for the information. I truly do appreciate it and use it to make decisions for future purchases. Take care, have a great weekend and God bless.

[@ericasedc]

S35VN is a great like… budget steel. It just doesn’t excite me like other steels do!

[@timtitus2532]

Still haven't obtained a blade in Magnacut yet. Have the other 3 and CRUWEAR as well as 3V. S90V is very tasty. I love it. Good video about the different steels. Haven't had any of the issues that you've mentioned, but my knives only see light use for the most part. I think the worst experience I've ever had on a knife edge was with AUS 8 many years ago. I lost a big chunk of the edge when I was cutting up some cardboard. Good video Erica. Thanks

[@glockgaston2922]

Really good video E!! I agree with you on the stainless steels and how they loose their bite if you go to a higher edge finish. I still haven’t had the chance to try out magnacut yet so I can’t say how it reacts to different edges. I personally really enjoy a lower edge finish for any of my stainless knives that I own because I like a toothier edge. Thanks for sharing and have a fantastic weekend!!

[@rob10ring]

S35 really seems to be where a lot of the foreign, cheapish knives are going, so at least it’s a step up for them. I’ve had some good knives in all of these and have even carried an old S30V PM2 for the last couple of weeks. Another similar steel to these that I’m really enjoying is Spy27. Even though I have a Magnacut Native, I’ll often choose the Spy27 version instead. So great to have these choices. In the early 90s, our “super steel” was AUS 8.

[@ericasedc]

I love Spy!!!!

[@joannearduin7801]

[@marccohen5579]

Unlike the 3V, CruWear, and M4, CPM 30V, S35VN, S45VN, 20CV, S90V, and S110V steels are all stainless to some degree. This is essential when you live on a boat in the ocean. I just picked up two Vanax knives to see how they'll do. My first knives were limited to H1. The only good thing is that they never rusted, but they could not keep an edge.

[@ericasedc]

Yeah H1 wasn’t my jam either!

[@jcolterh]

I sharpened my first S35vn today. Brought it up to 800 grit. Got glassy. Never knew what that term meant until today.

[@ericasedc]

Now ya know!!!! I dislike glassy edges.

[@sinepari9160]

SPOT ON assessment. XHP has become my favorite on folding knives but I'm a big D2 fan so, they call it stainless D2....XHP is is just perfect steel for me in a lightweight knife. My other large knives are S3V and Magnacut.

Now, if we could just convince Spyderco to ditch S30V and use Magnacut on their standard, non-Salt models. Benchmade will never give up S30V, they use it on most everything.

[@ericasedc]

Exactly!

[@Krozin]

i think the biggest thing i ever learned in collecting knives is that there can be a burnt edge on something that is over $100.

[@ericasedc]

Yes!

[@acid6urns]

i mean, these knives are mass produced man. they’re gonna be sharpened on belts, hand sharpening would knock the price up massively and decrease availability.

Hey Mike!!!❤

[@Knife_guy]

Magnacut really did throw a wrench into CRK and Spydercos plans. CRK was using S45 and Spyderco was starting to move models into S45 from S30. Now it seems like they have to go to Magnacut asap just to stay relevant. Literally almost every company is now starting to offer it in one model or another.

[@ericasedc]

I know!!!! Crazy

[@acid6urns]

i mean spyderco is still running s45 on their base models and it’s still a sick steel. the magnacut is only showing up on their salt line

[@Warsmith_Honsou]

S45 still default steel for Spyderco. Now they use magnacut but for salt series.

[@arrowheadguys7637]

I giggled the 1st time I ground a cruwear and magnacut blade. People make them out to be difficult to grind and eat up belts, but tbh I noticed no difference grinding them as I did AEBL, 1084 or 154cm. Its true belts will burn out quicker on it, but its not terrible. Regarding price, you'd probably be surprise how little price difference there is between Magnacut, Cruwear, S35vn and S45VN. Actually most the cpm steels are priced close enough its negligible when using it as a factor on what steel to buy. Other than S35vn, which is one of the most expensive for some reason, and a terrible steel. One thing that needs to be added to the conversation is heat treat, as a low heat treat can not only negatively affect edge performance but also reduce stainlessness. So those stainless steels that rust easily are probably run very soft. Magnacut over 63hrc should be virtually rustproof, there have been saltwater tests on properly treated MC blades that demonstrate this. But above all else, yes, Cruwear needs more love in the knife world.

[@ericasedc]

Yes I should have clarified further that we were talking about production knives. I mentioned later in the video that I would like to see some custom makers use S45VN more etc because we were talking about production knives during this. I will try to elaborate further next time! I loooove Cruwear!

[@arrowheadguys7637]

@@ericasedc Its sad that these companies can push shit heat treats on people. Benchmades new "water" series in 61 hrc Magnacut is going to be a disaster to anyone who uses it in salt conditions

[@Passively-Prepared]

Just commented the same message on “one of your old LC200N videos” lol so I’m copying and pasting it here because this was the very next video I clicked. So if you answer it there obviously don’t waste your time answering it here. But this being significantly more recent, I figured I had a better chance of your seeing it: From the knife steel nerds, knife steel ratings page, (I know he doesn’t have SPY27 on there but I’m assuming it’s in between S30V, S35VN, S45VN) it would appear LC200N is noticeable more tough and corrosion resistant than SPY27. It also appears SPY27 has noticeably better edge retention. From this video, it’s not clear so that’s why I’m asking for clarification, but is it in your opinion that toughness and corrosion resistance are for all intensive purposes close enough, and SPY27 gets the edge on the edge (no pun intended)… or is it if you really want to use and abuse your knife LC200N is actually noticeably tougher and corrosion resistant? I’m not buying my knife for the sole purpose of a pry bar or to leave it in the bottom of the bay for a month, but I want a knife I can just use as a strong piece of metal. I want to be able to dig and poke and wedge without thinking twice. I want to get God knows what liquids on it and not have to worry about rust if I forget to clean it for a few days. Can SPY27 handle that? Because I will take better edge retention if so. If not LC200N seems really attractive. I’m coming from the perspective if it’s not a fixed blade, it may as well be a slip joint Swiss Army Knife. But this Native 5 platform seems really really strong and if LC200N is as tough as the knife steel nerds ratings suggest, and also literally stain proof, and the edge isn’t as soft as a Swiss Army Knife, it sounds like as tough of a folding knife as one could get. But if SPY27 is close enough in toughness and corrosion resistance I will absolutely take the edge retention and blue handle that will blend in with my jeans lol.

@@Passively-Prepared Spy27 will do just fine

@@ericasedc so SPY27 Para3 vs LC200N Native 5… you would say there is a toughness difference, but the amount of force that would have to be exerted to see the difference would be so stupid and significant that it virtually doesn’t matter?

@@ericasedc I don’t mean to be pestery, but all I can do is try to find a store that even has a Para 3 and a Native 5 and hold them each for a minute and see which one feels better. I try to watch stuff like yours and others to help make these decisions.

[@ShelleyRaskin]

Interesting thoughts, remember s30V is not knife steel, its machining steel, made for industrial applications (same as most steel that we knife makers use), whereas thew other three you mention are actually made for edged tools.

[@ericasedc]

Wrong. In 2001, CPM interviewed many known knife makers including but not limited to Chris Reeve, Ernest Emerson, Paul Bos, Bill Harsey, and more to create CPM S30V which was supposed to be similar to 154CM but increased properties including a Vanadium content of 4%. It is a knife steel. Research! Thanks for watching!🥰

[@ShelleyRaskin]

My research says that is what happened with s35vn, the research was conducted earlier but the economies of scale meant that were trying for a machine steel (think plastic cutting and stamping) that would also have knife properties as the icing on the cake, it did not really achieve the desired result, although it’s great for plastic. S35vn was dipping their toes into the water and from a makers perspective it’s good, although so is elmax, rwl34 and of course AEB-L and the spin off nitro v. I have had success with polished edges on s30v, although I prefer elmax. I think the Swedes tend to keep their stuff cleaner, although Dr Thomas does not seem to think so. I have yet to give magnacut a try, although it’s on my wish list and Dr Thomas has given detailed heat treatment advice.

[@ericasedc]

@@ShelleyRaskin I think you may want to try researching again then. S35VN didn’t come around until 2009. Way after S30V. I’m not entirely sure where you’re getting your information- but it’s inaccurate. S30V was literally made for knives. Chris Reeve years later conducted the making of 35 with Crucible as an improvement to 30. Like you can literally read all about this evolution online. Or watch videos on it with Chris Reeve himself!

[@chrisreuther4546]

I feel like WRKT has had incredible success with S35VN… and you note that there isn’t a place but you just did a video where you are rocking 20 or so knives in a mystery 420ish and 1095. I’d say each steel has specific traits that work for specific uses
