Edge Retention Edge retention is really where the D2 steel shines. And - and this is not a popular opinion - S110V isn't necessarily better than S30V. The D2 Dozier hasn't shown any corrosion,even when i used it mainly in the kitchen cutting,slicing and dicing,even for a toolsteel. CPM S30V . However, there is a slight difference as to which one is going to be sharper than the other. For your folding knives, you can prefer steel with better edge retention. Feb 14, 2021 | Uncategorized | Uncategorized The blades are all of similar widths, around 2.5 cm, give or take amm or two. Exhibiting very good edge retention, corrosion resistance, and sharpenability, S30V is utilized by a variety of makers for its performance and balance. What it is: Crucible resistance, corrosion resistance. ... With a high level of edge retention, corrosion ⦠In operation since 1998, BladeForums.com has led the industry since Day 1. Both D2 tool steel and S30V are top quality metals that are normally found in the more high-end blades out on the market. BladeForums has ZERO TOLERANCE for extremism or calls of violence. You can use this chart to try to find the best steel for you. Once you sharpen a D2 steel blade you will find that this bad boy will keep its fine edge for a long long time, far longer then your S30v typically would. Edge retention testing between 8cr13mov spyderco tenacious and s30v spyderco sage 1. Even then, some localized rust would be more likely (where the film is lacking), as opposed to full on rust... 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. [citation needed] Used in most of the 2013 and forward Microtech knives. I previously wrote an article on what CATRA testing is and what it is revealing from a set of tests on 154CM: Maximizing Edge Retention.The CATRA edge retention test uses the slicing of 5% silica-impregnated cardstock and therefore tests slicing edge retention. 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. Many have found (including me) that the S30v will be able to get that slightly finer and sharper edge then the D2 tool steel, however not by much. The only area where D2 has an advantage over S30V is in ease of manufacturing. However, my favorite would have to be the D2 steel just because I find it to be slightly tougher and more reliable then the S30v but I own knives with both metals and half the time I can barely tell the difference! I can easily get a shavingsharp edge on this D2 folder. 1. ; 15.25% of Chromium: For tensile strength and Edge retention⦠440C: A high-chromium stainless steel with a terrific balance of good hardness and corrosion resistance. In any case, d2 is hardly a "high risk" for rusting, as some passive film is formed. It sharpens easier and is cheaper while still having a pretty great edge retention. CORROSION RESISTANCE: 7/10. Elmax is very similar to M390, CPM 20CV, and CTS 204P, but has somewhat lower Vanadium content, and lacks any Tungsten content. This does not bode well as edge retention is a top, if not the top, priority for knife fanatics. However, they both have their perks and are better in different ways and for different situations so you really need to know what you are going to be using it for before you make your decision. S30V can also support more acute blade/edge geometry, which improves edge retention, cutting performance and ease of sharpening. S90V has a better edge retention but let's all be honest, edge retention for most of us is just numbers on a piece of paper. I would argue that S30V is better for every practical need. A good choice for hard use applications. Spyderco Salt I Plain Edge Yellow H-1 Steel Knife Review, Spyderco Sage Carbon Fiber Plain Edge Review, Some Throwing Knife Targets to Choose From, Top 5 of the Most Expensive Pocket Knives, Winter Tent Camping – What You Need To Know, Best Coleman Instant Tent For Family Camping: Buying Guide. S30V is, in many eyes, the ultimate EDC steel. CPM S35VN's improved toughness gives it better resistance to edge chipping. HRC: 59.5â61. EDGE RETENTION: 7/10. Whereas S30V steel is what is considered to be stainless steel meaning that it will be more restitant if not 100% rust and corrosion resistant. CPM-S30V. This means you are going to have a super sharp edge for the majority of the time and your not going to have to sharpen it as often as you would with S30v steel. D2 is an excellent knife steel. I threw in S110V to define the top of the range in blade sharpening difficulty and tenacious edge retention. As unsurprising as these statements are, it was heartening that my tests at a very basic level werenât putting 420HC above S30V or anything particularly unexpected. 440C takes a nice edge and is fairly easy to resharpen. Maxamet Vs. S30V. Advantages: Wear 420hc's main advantage is its relatively high edge stability, D2 is among the worst steels for edge stability, meaning it chips easily if the cut ⦠Select Page. It's a rare occurrence that we need that level of performance. Although I've been using and carrying knives since I was a little kid, I'm still in the "learning a lot" stage about blade steels. Your email address will not be published. However, on the other hand, most people find that the d2 is easier to sharpen the S30v so if you are a beginner or not that an experienced of a sharpener then it should be something that you consider. Furthermore, the D2 steel isn’t as brittle and more likely to chip or break as the S30v would as it is a tougher quality steel. The closer to 20 points the âbetterâ the steel. d2 s30v; edge retention: 3.5/10: 5/10: ease of sharpness: 4/10: 5/10: corrosion resistance: 4/10: 7/10: toughness: 6/10: 6/10 In regards to the data there are two ways to look at the performance of S30V vs VG-10 : how they compare at the same angle how they compare at the same edge retention At the same edge angle, S30V has 31 (12) % increased edge retention over VG-10. if i have to compare edgeholding on the Native S30V and the Dozier D2 folder,its very much the same,from my use and experience. S30V . Details on the knives used : As the Fällkniven knives S1 and WM have full convex grinds there is nodistinct secondary edge bevels. Martensitic is a specific type of stainless steel alloy. CATRA Testing. Think of CTS-XHP as a more corrosion resistant form of D2 steel with marginally superior edge retention. TWISTED SISAL MERCH - THANKS TO MISHEARDKNIFEREVIEWS: https://teespring.com/twisted-sisal-merch Remember to subscribe for more lunacy - ⦠D2: An air-hardened tool steel, which offers good corrosion resistance and excellent mileage in wear resistance. TOUGHNESS: 5/10. As from features, VG10 steel is the best balanced blade steel for everyone. S30V is better. That means going for a tough steel like CPM 3V for a chopper, an edge retention focused steel like CPM S30V for your folders, and a super stainless steel like H1 or X15TN for your marine-use blades. I decided to do this on 20 point scale, where I assign a maximum of 5 points to the 4 categories of Ease of Sharpening, Toughness, Edge Retention and Corrosion Resistance. 20 Posts . Thanks to Mark McKinley and Alfredo Faccipieri for becoming Knife Steel Nerds Patreon supporters! ... D2 has been around for more than 20 years, an eternity in metallurgy terms. Because of its high durability, high corrosion resistance and edge retention, Benchmade Knives entire new line of premium hunting knives, appropriately called the HUNT series, are all made with CPM-S30V. Overall, both the D2 tool steel and the S30v are top quality metals that are going to serve you very well. Chris Reeve is famous for developing two steels directly with Crucible Industries, and boy did this partnership result in an awesome product. Furthermore, if you are looking for a larger blade, then I would recommend the D2 as in most cases the larger the blade is, the less suitable S30v steel comes for it. These things were unsurprising to me and probably will be to anybody with an existing interest. SHARPENING EASE: 5/10 We request your assistance dealing with this as we do not want to see the site shut down due to violent threats. I decided to do this on 20 point scale, where I assign a maximum of 5 points to the 4 categories of Ease of Sharpening, Toughness, Edge Retention and Corrosion Resistance. 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%. ). It has to have a certain amount of chromium to attain a full passive film, and by some standards even, d2 does have enough, however it's the bare minimum, (by most modern standards it falls just short), but due to the high carbon levels some of that chromium gets trapped into forming carbides (which aid in cutting esp. Maxamet has amazing edge retention, as does ZDP189 and CPM10V. This is in agreement with the CATRA data from Crucible. Please see this thread here in Tech Support: D2 is "almost" stain resistant... Chromium forms what is called a passive film, a thin chrome layer over the Steel's surface which gives stainless steel it's "stainlessness". s30v d2; edge retention: 5/10: 3.5/10: ease of sharpness: 5/10: 4/10: corrosion resistance: 7/10: 4/10: toughness: 6/10: 6/10 The main difference between the two metals is that D2 steel is what you would call tool steel which means that it is not a resistant to the elements and, as a result, is more susceptible to rust and corrosion. However through the width of the edge bevelon the F1, the S1 and WM are thinner, and thus have a more acutely formededge. D2, is a high carbon, ... Often said to be superior to CPM S30V and CPM S35VN for edge retention and ease of sharpening. (My opinion on how D2 sharpens is supported by the Crucible data sheet for S30V, wherein it is stated that the grind-ability of S30V, "is comparable to that of D2.") However, if you take good care of your D2 you will find that it will stay corrosion free and work just as well the S30V in this regard, although if you don’t want to spend a lot of time cleaning the blade then you would be better to go for s30v steel. Relative Values Edge Retention (CATRA Testing Relative to 440C) Grade % CPM S30V 145 154CM 120 440C 100 ... 440C 154 CM CPM S30V *vs. Hg/HgO reference electrode Slightly better edge retention than S30V and but a little more work required in the sharpening process. Like D2, however, itâs not easy to sharpen and can be brittle (prone to chipping). In general, I didnât change the austenitizing temperature much when comparing the same steel at different hardness so the trend of hardness vs edge retention looks about right for steels like S30V and 10V. It works pretty well (albeit a bit slow) on S30V. >> See knives with CTS-XHP steel. So that austenitize-temper decision can affect the final properties in terms of toughness and edge retention even when at the same hardness. Unless you completely neglect it, leaving it wet for a length of time, it will still resist rust quite well. Now both of these steels will make for an incredibly sharp blade, no doubting that. Both metals are going to give you a strong and reliable blade with good edge retention and a high level of sharpness. less costly than S30V and doesnât have quite the hardness or toughness of the latter Large carbides in this all-around premium knife steel make it take and hold an edge extremely well; it is also very tough and wear resistant. Once you sharpen a D2 steel blade you will find that this bad boy will keep its fine edge for a long long time, far longer then your S30v typically would. Because both vanadium and niobium carbides are harder and more effective than chromium carbides in providing wear resistance, the CPM stainless blade steels offer improved edge retention over conventional high chromium steels, such as 440C and D2. Discussion in 'General Knife Discussion' started by pjandyho, Feb 2, 2016. Edge retention is really where the D2 steel shines. s110v vs s30v. That is good all-around knife steel. Best VG-10 steel knives Spyderco Dragonfly 2 The Sebenza 21. By popular request I have created a steel chart, where I try to simply map out the relative merits of each steel. Discussion Starter ⢠#1 ⢠Feb 15, 2007. This is the final word on these two knives..I believe.
