In today's steel test, I put the newest rust proof steel, LC200N, up against an EDC juggernaut, S30V. When you put your knife to work, what tasks will it need to conquer? The 400 Series of steel has been popular for longer than almost any knife guy has been alive. Often overlooked is the job at hand. Crucible Industries has a real gem on their hands with CPM-M4… At the cost of some corrosion resistance you get amazing edge holding, toughness, and decent enough sharpenability. M390 vs S110V or something else? In a hurry? S110V=26 Maxamet=24 M390=26. Compared to forged steels, powdered metallurgy based CPM steels have a very fine grain structure and far fewer inclusions. https://www.bladeforums.com/threads/bladeforums-has-a-zero-tolerance-policy-towards-threats-of-violence-extremism-be-warned.1769537/, (You must log in or sign up to reply here. Are you in a humid, wet, and salty environment? A2 has long been known as the classic standby for a fixed blade steel. S110V has a similar Mo content as well so it should still have better corrosion resistance than S45VN. When it comes to getting the job done there are four main factors that determine steel quality. S30V is unique and notable because it was developed specifically for knives. A 30 degree inclusive edge means that each side of the blade is sharpened to 15 degrees. This allows for a very uniform distribution of carbides throughout the steel structure during solidification. Martensitic is a specific type of stainless steel alloy. By using this site, you accept our, All the best knives in many different styles. In operation since 1998, BladeForums.com has led the industry since Day 1. You can't go wrong with this timeless tool steel. This blade steel exhibits good toughness, but it does not meet the level of M390. Good edge retention, toughness, and sharpenability, D2 has been a popular knife tool steel dating back to WWII, and for good reason. M390 exhibits excellent edge retention, corrosion resistance, and high level toughness. S110v vs s30v I plan on getting a Spyderco co paramilitary 2 or para 3 and I was wondering about these 2 steels. S90V VS S110V. Generally speaking, the higher the number at the front, the better the steel. Popular among both Benchmade and Spyderco, CPM-S90V is a knife steel known for its excellent edge retention and very good corrosion resistance. ← Knife Facts: Is s110v better than s30v? Performance of all the 400 Series steels is quite similar, but you will see slight variations among the different compositions. Exhibiting very good edge retention, corrosion resistance, and sharpenability, S30V is utilized by a variety of makers for its performance and balance. I have two Spydies in this steel and they are not difficult to sharpen. The comparison between the two is tough. With slightly decreased edge holding and a tendency to corrode in extreme conditions, O1 performs very well despite requiring light maintenance. 10V. Strength and toughness are comparable to that found on VG-10 or 154CM. Any of these blade steels are 100% good to rock and roll. VG-10 exhibits many of the same qualities of 154CM with the largest difference being an increase in corrosion resistance. CPM-20CV can be found on my knives today and is made by the USA-based Crucible Industries. The difference with H1 is that you can literally leave it in salt water forever and it won’t rust. OTHER GEAR REVIEWS: Comparing the Magnum 7mm vs. 30-06 Springfield, Reviewing the Lee Loadmaster vs. CPM-S110V exhibits many of the same qualities as S90V. Martensitic is a specific type of stainless steel alloy. CPM-S110V. Cruwear Steel is known as a SUPER STEEL, and I share the same opinion, it has very well balanced properties (hardness, edge retention, wear resistance, toughness, corrosion resistance), but let me remind you it’s a high-end steel, so Cruwear knives are a bit expensive (Which is understandable), so if you intend to buy or to own one, again I highly recommend it. Both of these steels are a real bear to sharpen up! This steel has extremely good corrosion resistant properties. Remember that in addition to steel, geometry and heat treatment both play a huge role in performance. Easy to sharpen and quite corrosion resistant, maintenance is a breeze. S110V is slightly better in terms of corrosion resistance and toughness compared to S90V. Toughness is key on hard-use camp knives and fixed blades. Thanks to ShavedAlpaca, giorgi chubinidze, and Сергей Якунин for becoming Knife Steel Nerds Patreon supporters!. Heat Treatment is the process of hardening and tempering the blade steel through heat. If you need corrosion resistance, go with s110v or even s30v. Pro 1000 M390. Both great steels, CPM-154 benefits from a powdered metallurgy and is finer grained than 154CM. This is not so for the rest of the SxxV line. I use a Sharpmaker. 1095 is budget-friendly and widely available. This comparison conveys the largest gap in edge retention, as private reviewers were unhappy with how quickly the S30V blade became blunt for general cutting on typical items like rugs. The best blade steels exhibit a balance of strength and toughness. Buck widely uses 420HC in their knives to great success. Cutting and slicing performance improves as the thickness behind the edge decreases. There’s no doubt—H1 is a specialty steel. Crucible Industry's CPM stands for Crucible Particle Metallurgy. Sharpenability is pretty self-explanatory, but softer steels can be touched up in the field on that big elk hunt. From designer to country of origin, blade length, and beyond, there’s a plethora of different factors to consider when buying that fancy new knife. Finer grained powder steels can take a sharper edge. Additional considerations include the thickness of the blade stock and the primary grind. Use it. This does not bode well as edge retention is a top, if not the top, priority for knife fanatics. Touching up certain steels with your sharpening stone is an easy, pain-free process whereas harder steels can make for an all-day affair to bring them back to sharp. Elmax can be found in many Microtech knives. The vivid patterns visible in Damascus steel come from the acid etching process in a ferric chloride solution. When it comes to edge retention, S90v steel is far better than S30v steel as it can stay sharp for an incredible amount of time. Insanely tough, this steel also manages to boast excellent edge retention and corrosion resistance. Personally, all of these steels are really good. Paid Subscribers don't see ads! Sandvik steels are largely found on affordable, entry-level knives. Blade steel is totally a super important factor to consider when buying a knife, but wait a second—it isn’t the be-all, end-all. Essentially, CPM steel (also called powdered steel) is produced from a very fine powder of carbide particles. MFL It doesn't really have any benefit over s110v. Is blade steel a mystery to you? Though the margin of difference between the two is not that great it is noticable. But what is the best knife steel? Extremely tough blades may not cut as well as desired and can suffer from edge rolling and difficulty maintaining an edge. The following are deserving of mention, but there are just not enough knives produced from these steels to give a rating. Thank you for quick test between S110V vs. S90V, but Spyderco bevel geometry and HT differ quite a bit from BKC. Knife steels that exhibit extreme hardness and edge retention are amazing at cutting through warehouses full of cardboard but hit a staple and your knife may suffer a chip. A tough blade steel resists chips and total failure when subjected to beating, impact, twisting, and torsion. Isn’t this video I do a toughness test on three different Spyderco’s with k390, cruwear, and S110V. So what is the best steel for knives? Inherently, more acute sharpening angles will see better cutting performance than more obtuse angles. Powdered steels are more consistent, have better edge retention, and improve toughness due to a lack of inclusions. CPM-154 is an excellent EDC blade steel with above average edge retention, corrosion resistance, and ease of sharpening. Knives prone to corrosion can be protected with a thin coat of mineral oil. If you don’t, the cruwear or m4 is great. Damascus or ‘pattern welded’ steel is a result of combining two steels together. Just keep in mind that knives made from AUS-8 are generally very affordable. As you’d expect the carbon content is very high but the secret here is the extreme quantities of vanadium, almost three times that found in Elmax or S30V. It really depends on what you're doing with your knife. S110V's data sheet mentions, for example, that it has better corrosion resistance than S90V. The 11V steel would still be an upgrade over S90V for corrosion resistance because of the higher Mo in solution (see the Molybdenum section later on in this article). The primary difference is out-of-this-world edge retention at the cost of a minimal reduction in toughness. The specifications of these samples can be viewed here. Don’t know 20CV from M4? Martensitic is a specific type of stainless steel alloy. Spyderco and Cold Steel frequently utilize this steel and the chart below shows why. With 90% the corrosion resistance of H1, you also get much improved edge retention. Compare your use cases to choose the perfect knife for you. Edge Retention. Abuse it. BD1N is a completely different steel. experience. What's your favorite steel on your pocket knives? S90V VS S30V Certain steels are so good at resisting rust and corrosion that they can be left abused and salty without ill-effect. Bohler M390 is widely revered as being the best all-around knife steel, which has led top companies to widely utilize it in higher end knives. Tough steels excel at camp chores and batoning wood but are unable to be used at very thin edge profiles while maintaining edge stability. The goal of many knife users is to find the best steel to fits their needs. As such, the performance of the steel is entirely dependent upon the steels being utilized. 2.8% of Carbon: It improves hardness and wear/corrosion resistance, but a high amount of it decreases strength. All you have to do is click to be taken to Just go over our comparison between S30V vs. VG 10 above so that you can finally decide what type of steel you need for your knife. However, S90V and the modified S110V (labeled 11V) have 11.5% Cr in solution while S110V (9Nb-3.5Nb) has 12.3% Cr in solution, which would provide better corrosion resistance. BD1 is a great entry-level steel. ). Below shows the results of CATRA experiments reported by others that I have shown in other articles. It may seem like there’s a big step down between a steel like S110V and CPM 154. M390 vs S110V: I have a knife with M390. In contrast, a more obtuse angle will be more stable and durable. S30V will be easier to sharpen in general, but S90V will hold an edge for longer while not being that much harder to sharpen. Yes it’s ridiculously expensive, and yes it requires the patience of a saint to sharpen but outside its less common cousin CPM-S110V (see above) nothing holds an edge or withstands abrasion quite like CPM S90V. Edge retention and toughness are very good. Good to hear so far. Blade HQ uses cookies to provide you a better user Sharpening goes hand in hand with blade geometry. Where a normal steel would chip, these knives can sustain intense batoning sessions, power through staples, and glide through steel strapping. The main changes we expect from S45VN vs S35VN and S30V are an improvement in corrosion resistance due to the increase in Cr of about 1%. Toughness. ; 9% of Vanadium: Improves wear resistance and hardenability. No one would ever confuse AUS-8 for being premium, but that's okay. S30V is easier to sharpen, so if you're not used to high carbide steels, S110V will prove quite difficult. Whether it’s dicing up cardboard boxes, feather sticking some firewood, or hacking up sisal rope, no one likes a dull knife. That also depends on who you get the knife from, heat treament etc. Carpenter-produced CTS-XHP is one of the most well-rounded and versatile steels. Tough blade steels are ideal for camping and hard-use. I get it. Discussion in 'General Knife Discussion' started by percula9, May 26, 2010. S30V and VG 10 are great materials for a knife blade, but it’s up to you to decide which one is better. 14C28N may be an improvement over 12C27, but realistically the performance between the two is not significantly different. The effect of heat treat varies based on the composition of the steel. S110V. BladeForums has ZERO TOLERANCE for extremism or calls of violence. CPM S110V Steel Chemical composition . There are a million out there, and this page will surely be updated over time to include more. S90V has similar toughness to other PM stainless steels like S60V, S30V, and M390. 1095 has long been popular among knife makers for its easy workability, high toughness, and good edge holding. The charts below aid visualization of the strengths and weaknesses of a particular knife steel. S30V is, in many eyes, the ultimate EDC steel. Carbon steels will pit and rust aggressively in wet environments if not properly cared for. A well-done and consistent heat treat goes a long way towards the performance of a knife. The great thing about cutlery, is that any knife can get equally sharp regardless of steel. On January 15, 2020 Spyderco announced [1] knives being produced in a new steel: CPM SPY27, a steel produced by … If you’re interested in the perfect fishing knife, look no further. Update 3/10/2020: We did a range of experiments with SPY27 to supplement the estimates in this article. If your favorite designer makes a knife in one of these steels, don't hesitate to pick it. This is one of those most ubiquitous steels in knives. S125V. Give this article and each knife steel chart a gander, and you’ll be halfway to an Ivy League degree as a metallurgist (no uhh…not really, but we all start somewhere). Maxamet Vs. S30V. LC200N is an amazing steel! Given a choice between the 2 steels everything else being the same I would choose S90V. Equally at home as an EDC folder or as a fixed blade, this blade steel is easy to sharpen, corrosion resistant, and mixes very good edge retention with sufficient toughness. It's just a consequence of s30v hype blowback. Don’t worry—we’re going to break down and compare all the best knife steels you can expect to find at Blade HQ so that you can determine the supreme steel for your needs. Bohler-Uddeholm produces more than just the famous M390 steel. 154CM. Realistically, in normal day to day use you would struggle to pick out any differences in comparison. S90V VS M390 M390 offers better corrosion resistance, higher toughness, and the same level of edge retention compared to the S90V. Not widely offered by knife makers yet, BD1N would likely land in the Premium or High-End section of our article, and is found in the highly-anticipated Spyderco Para 3 Lightweight. It's been VERY noticeable for me in NORMAL kitchen use between S90V and S110V, that's S90V at 60 HRC and S110V at 65 HRC, both knives are .006" behind the edge. 22:06. Blade steels with an insane amount of hardness (pushing towards 70 HRC) tend to lack stability and can suffer from cracks, chipping, and total failure. M390 is super stuff, I always want more CPM-M4 in my life, and there's never going to be anything wrong with a fixed blade made out of A2. Buy it. If you find a knife you love in AUS-8, it's okay! They are really good and you don’t pay a premium to get them. Sharpen it! Consider Elmax if toughness is high on your list. ; 2.25% of Molybdenum: Increase Machinability and strength. It would be ideal to test both steel in same model. If you frequently use your knife to slice up cardboard, there may not be a better steel than CPM-S110V. With significant amounts of Chromium, Molybdenum, Vanadium, and Tungsten, these steels are 100% ready for action. And - and this is not a popular opinion - S110V isn't necessarily better than S30V. N690 is an extremely ubiquitous and popular steel among knifemakers in Europe. It works pretty well (albeit a bit slow) on S30V. Look at the data sheets from Crucible, which I have linked here: S110V, S90V. Hone your sharpening technique and expand your collection as these steels are generally more affordable. I read somewhere that s90v holds an edge but the edge isn't that good at certain tasks because the molecules in the steel are jagged or something (this was a long time ago) so I was wondering if s110v did something like that and if I'd be better off getting s30v or s110v. This comparison conveys the largest gap in edge retention, as private reviewers were unhappy with how quickly the S30V blade became blunt for general cutting on typical items like rugs. Certain blade steels are more stable at highly acute angels. You can’t go wrong with either of these great steels from Crucible. The most well rounded steels like CPM-154 and 154CM create an even shape while a steel like CPM-3V is severe due to high toughness and lower scores in all other categories. An easy to sharpen knife will generally not exhibit excellent edge retention. Both S30V and S35VN steel are made with the same carbon and chrome content, and from various tests, both steels provide the same edge retention and corrosion resistance. 110v is hypothetically more brittle because it has more stuff. Do you frequently use your knife to meal prep acidic ingredients like citrus or tomatoes? In head-to-head testing, you would struggle to discern a significant difference between the two knife steels, but under a microscope you will see improved toughness and sharpenability (S35VN is a dream to sharpen when compared to S110V). Maybe one of the most frequently overlooked aspects of blade steel is sharpenability. Becker BK2. ; 15.25% of Chromium: For tensile strength and Edge retention, and enhances corrosion resistance and wear resistance. Steels patina in the acid at varying rates which allows for one steel to etch darker than the other and show that famous patterned contrast. If you frequently use your knife to slice up cardboard, there may not be a better steel than CPM-S110V. S60V. Compared to CPM-3V, A2 is available more much affordable and is much more easily sharpened. The following is a list of popular budget steels. Pro-tip—if your blade is labeled stainless steel, but no more details than that, you're probably best off keeping that knife decorative only or using it as a beater knife. When we call a normal steel stainless, it really means that the steel will stain LESS than carbon steel. The razor edge was gone after very little cutting, more like what I expect from S35VN and S30V. In reality, there is no perfect blade steel in the same way that there is no perfect knife. Each has its own strengths and weaknesses. It’s remarkable the increased performance you find in cut tests when comparing premium steels to lower end options. Does Bohler-Uddeholm sound like a stinky cheese to you? S60V. ... To me S110V performs like S30V on steroids, and funny enough Ive had worse chipping issues with S30V on the exact same knife pattern. The chart below shows how amazing H1 steel is in every category except edge retention. M390 vs S90V (CPM S90V) M390 Benchmade 20cv is outstanding in my book. We have tested S90V and S125V toughness with our standard test using 1/4 size unnotched charpy specimens. After cutting up the coconut the edge seems to be holding up well! In short, you cant go wrong either way. S110V=26 Maxamet=24 M390=26. that section. CPM-4V boosts the edge holding when compared against 3V, but at the cost of some slight toughness. The primary difference is out-of-this-world edge retention at the cost of a minimal reduction in toughness. For those in wet and humid environments, that's usually not a deal breaker. Believe me, we tested it so you don't have to. Is Crucible still just a play by Arthur Miller in your mind? A knife with great edge retention will vaporize cardboard even after months of carry. O1 is a small step below A2 in terms of blade steel performance. I'm just saying. The M390 one is a bit more exclusive if that matters to you. Such amazing corrosion resistance comes at a cost, as this steel doesn't exhibit stand-out wear resistance, edge holding, or toughness. AUS-8 can be readily found in one of our best-selling knife models, the Boker Kalashnikov. I can t personally judge the tendencies for chipping. Knives such as the Spyderco Chaparral have a very thin edge at only .014”. I touch up when the knives don't pass my simple sharpness test, if the knife will slice though a paper towel length wise while holding it without tearing it then it's sharp enough.  Originally developed by both Chris Reeve (a world renowned knife maker) and Dick Barber of Crucible Industries, S30V is a martensitic powder-made stainless steel. CPM-S30V has become one of the most used premium steels on the market among knife manufacturers. Edge Retention (also called strength) is your knife’s ability to hold sharpness during use. This is a small list of steels that aren't necessarily in high production anymore, but still offer high-end or mid-range performance. However, S30v steel is much easier to sharpen, and some people find it to be a more practical option … S90V could be called a super steel (at least thats what I call it) while S30V is a great steel and better for ease of sharpening, you will however have to sharpen it more and it wont take as good of an edge as S90V. S90V. In contrast, a thicker blade stock with more material at the edge will yield a tougher, less slicey knife like the Ka-Bar S35VN VS S30V. S90V offers high edge retention with low toughness and the same corrosion resistance compared to S30V. Low hardness increases toughness at the cost of edge strength. There have been multiple reports of chipping and rolling, which are probably due to S110V… While H1 steel lives in a specialist category as a fishing or boating knife, LC200N holds its own as an EDC knife steel. S30V VS D2 Excellent strength and toughness are balanced with very good sharpenability and corrosion resistance. AUS-8 steel. Blade geometry is a subject that deserves its own article, but here’s a summary. a mix) of carbon and iron that is often enriched with other elements to improve certain characteristics depending on the desired application. This increases the strength of the edge tremendously. Chris Reeve is famous for developing two steels directly with Crucible Industries, and boy did this partnership result in an awesome product. M390, 204P, and 20CV are all durable steels that sacrifice ease of sharpening. The edge retention of S30V is still pretty good relative to other knife steels, better than steels like XHP, Elmax, 154CM, 440C, etc. S110V vs S90V Discussion in 'General Knife Discussion' started by dkb45, Dec 14, 2017. Based on experience and testing, M4 steel may outperform blade steels such as M390 and S90V in terms of edge retention and M4 is in a completely different league in terms of toughness.
