This means that many of these “super steels” have inherently low toughness and therefore have difficulty with impact applications or in handling high stresses in thin edges. In the early bladeforums era, VG-10 was sometimes called a “super steel” [5] but I don’t see it called super much anymore [6]. Pete Winkler, owner of Cross Knives and a “Forged In Fire” winner uses A2. High Carbon Steel: Commonly known as “carbon tool steel” it typically has a carbon range between 0.61% and 1.50%. So here we go. Both steels are great. If the CPM 3v blade is thinner & lighter, but still as strong as the A2, then that would be an advantage. Sharpening is essentially the intentional wearing of the edge, and therefore high wear resistance “super steels” have poor sharpenability. You can rely on any of these knives. A quality tool steel knife will probably not need sharpening in the field if it is properly cared for and maintained. I have a Tops BoB Fieldcraft in 1095 that I use a lot, and it always sharpens up nicely. Because these steels are viewed as being superior, they are often perceived as also having high toughness despite their high wear resistance. This food-grade stainless steel straw cuts down on single use plastic and fits perfectly in even large 24 oz beverages. I used this Jesse Hemphill Custom Damascus to gut and skin an Oregon Mule deer.

While many decry the super steels as being unnecessary, the conflation of “high wear resistance” and super, or premium steel, continues. If the knife is used for its intended purposes, and not used as a pry bar, screwdriver, paint scraper, wire cutter etc. Difference Between Hot Rolled Steel and Cold Rolled Steel. But at what point does a designer or super steel blade become overkill and an added, unnecessary expense? In addition, Super Steel maintains extensive manufacturing infrastructure capability. Among his ten items for Season Two, Roberts chose to take the L.T. It is not possible to design steels that have both high wear resistance and ease in sharpening. Mike Stewart, president of Bark River Knives, says if he could only use one steel in his knives it would be  A2. The silicone comfort tip adds a pop of color and is molded to the stainless base, so it doesn’t collect dirt or fall off. This is a nitrogen steel that is extremely corrosion-resistant — so much so that it’s used in knives designed to go in salt water, among the most difficult conditions knives are used in. See this article for more information on articles that rate and rank steels. “There is nothing wrong about A-2,” he commented. In more than 50 years of using knives in the field, I’ve never broken a blade. Super Steel has been distributing Steel and Rural products throughout QLD, NSW, & NT since 2004. The L.T. For example, comparing AEB-L/13C26 to 154CM, CPM-154, and S30V, you can see a stark difference in carbide volume (grey particles): You can see that while the powder metallurgy process greatly reduces the size of the carbides in 154CM, it does not affect the amount of carbide. A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. Buyers often pass over the more common, less expensive knife blade steels in favor of the newer, more exotic types. My kids are grown up and gone, and my wife and I are empty nesters. Powder metallurgy and modern steel design offer “okay” or “good” toughness, high edge retention, and high corrosion resistance. Brass.

Sometimes non-stainless steels such as 3V or Infi have been called “super steels” [4]. A steel designation trademarked by Cold Steel, Carbon V reportedly fits between a 1095 and O1 grade and is similar to 50100-B. 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. This article is the first of a four-part series on the different types of steel.

In fact, those original knives most closely resemble the excellent Old Hickory carbon steel knives available at any box store. Furthermore, the hard vanadium carbides in many of the steels are harder than common abrasives like aluminum oxide (alumina) which further increases the difficulty in sharpening [18]: The term “super steel” has been around since at least the 70’s and it has been used both positively and negatively as far back as I can find. While smaller carbides do help with limiting crack initiation, toughness is still reduced by having a large volume of carbide. You can read more about the effect of carbides on toughness in the article I wrote on microchipping and in the summary of edge stability theory. You might find your grail knife has a tool steel blade! However, things are not going to be that perfect, it has very poor corrosion resistance due to its low carbide volume. Steel type pokemon attacks are not effective against the Steel, Fire, Water, Electric type pokemon. Vanadis 4 Extra seems great for a non-stainless steel. this article for more information on articles that rate and rank steels, https://knifesteelnerds.com/2018/06/11/how-much-more-chromium-does-d2-need-to-be-stainless/. It may be that the small niobium addition helps with refining the overall carbide structure, and Crucible has reported an improvement in transverse toughness vs S30V. What about s35vn? Extra edge holding is great but it then takes longer to re-sharpen. This is a stainless steel commonly used on many mass-manufactured pocket knives and represents a … Steel type pokemon are immune to Poison type pokemon. (That’s where the neat patterns come from.) “Extra toughness is kind of moot if you can’t break an A-2 blade. FEATURES. https://www.patreon.com/Knifesteelnerds, While many decry the super steels as being unnecessary, the conflation of “high wear resistance” and super, or premium steel, continues. I saw how many references to “super steel” there were in each year, and then as a proxy to how many posts there were on bladeforums I did a search for “154” and saw how many references there were each year. However, in comparisons based on wear resistance the “super steels” have poor sharpenability. YXR7 has less than 5% carbide volume and more than 5% MO volume, its hardness reaches HRC 65 or so to gain superior edge retention while having seperior toughness owing to its low carbide volume. The Uddeholm chart shows three different carbide contents along with the change in toughness with hardness; the three steels are Vanadis 4 Extra, Vanadis 8, and Vanadis 60. I’m referring to such excellent super steels as CPM 3V, CPM 4V, Elmax, CPM 154, CruWear etc. While a steel with a small volume of carbide can also have poor toughness, carbide volume can be thought of as setting an upper bound for potential toughness of a steel. For example, in the Knife Informer article rating knife steels [10], the steels are categorized from “Super Premium” down to “Low End” with the differentiating property being edge retention. If the knife is a user, it will inevitably get some dings and scratches and show some honest usage wear. The Crucible chart shows the change in toughness from carbide volume when each steel is heat treated to approximately 60 Rc. Many discussions on bladeforums about super steels continue to be about whether we need the so-called super steels or whether the old classics are good enough or even superior [7][8][9]. Steel type pokemon attack are weak against Fighting, Ground, Fire type pokemon. I see frequent references to “super steel” online, and I was curious about how long that terminology has been around.

The number of references to “super steel” has increased over time, but so have the number of posts on bladeforums. Steels like 3V and Vanadis 4 Extra get their combination of wear resistance and toughness by having a relatively small volume of carbide (<10%) but having all of those carbides be the very hard vanadium carbide. [12] Pinnow, Kenneth E., and William Stasko. Several key characteristics of a superalloy are excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation. It is the strongest type defensively, with 10 types being not very effective against it and the Poison type having no effect.

I have blades in all of these steels, use them regularly and don’t want to give them up. Toughness testing here at Knife Steel Nerds has also found unspectacular toughness values for M390, though it has only been tested at relatively high hardness: The reason why almost any steel will have relatively low toughness that is designed for very high wear resistance is the large amount of carbide that is present in the microstructure. However, ease in forging and annealing, and a high working hardness are advantages that the tungsten steels have. I have no real complaints, but I would consider shelling out the extra money for the super steel IF it were for the LT version of the Bravo. Different steels slowly lose the title of “super” over time. The blade was Carbon V, and it held an edge very well.
