Quite an eyeopener! Ive found S35VN less chippy even at the same hardness. Spyderco and Cold Steel have used it, though Cold Steel recently switched to S35VN due to availability concerns. This does not predict which knife will cut longer or be more resistant to chipping. AEB-L is rarely found on production knives but can be found on custom knives easily. As from features, for presenting d2 continue to grow in the knife industry, generally because of their working performance and reasonable price, a lot of superior low budget knives are building their reputation. It mainly made for knife and it high in Chromium for excellent corrosion resistance. Each test is done with 3 or more specimens to get a good average. Maxamet is one of two current high-hardness kings, with HRc marks in the high 60s approaching 70, a hardness usually only seen in carbide steels. Lots of information is still specific to this article, however. Goes to show that science not marketing or conjecture is what determines a good steel, 51shitty? Unfortunately a high amount of it decreases strength. I just want to thank you for all the work you do for the community and the world at large. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. The benefit of this, of course, is that the steel holds an edge for a very, very long time. The steel is similar to Sandviks 13C26. Are you okay with that? If the knife youre looking at has a 154CM blade, youre fine. Thank you for putting this together, incredibly useful! Also D2 is not stainless as at least 5% of its chromium is tied up in carbides where it doesnt help prevent corrosion. Let's compare 14c28n steel with other steels, and for this, I use four criteria; Edge Retention, Corrosion resistance, Ease of Sharpness, and Toughness and on a scale of 1-10 (10 being the highest) let's see the performance of each steel. Because of their good edge retention, these steels are quite versatile in folders and fixed blades. 0.62% of Carbon: Makes knives harder and more resistant. The highest edge retention steel was Rex 121 which was at 70 Rc in combination with lots of high hardness vanadium carbides. They lack the carbon necessary to hold an edge, even during mild use. Is 440A really that much better than 420HC, or have you found a narrower gap? Stainless steels are more resistant to corrosion but remember that stainless steels stain less, and most of them will still rust in the right conditions. Available in Kershaw knives (as of 2012) and in other . Fix-It Sticks Compact Ratcheting Multi-Tool Review, Toughness, Wear Resistance, Corrosion Resistance. Its a very hard steel and is exceptionally difficult to sharpen. However, in our testing there is a reduction in toughness by using the high temperature range rather than the low temperature range, such as was found with CPM-CruWear (Z-Wear) or CPM-10V. It is a premium steel that is known for its excellent balance of hardness, corrosion resistance, and edge retention. For this perfect size that for most tasks and the slim tip allows the knife to excel at piercing and detail work. Hi Jimmie, thanks for your comments. 1.4116 got a 2.5 for toughness and edge retention where as 420HC got a 9 for toughness and a 2.5 for edge retention. VG-1 is a non-powder steel made by Japanese specialty steelmaker Takefu. Which knife for best? So, its hard steel is easy to sharpen. But keep in mind that no steel is perfect for everything. There is no such thing as a steel that is a 10 in both toughness and edge retention. Im looking forward to seeing if it does as well in full production. Display: 24 per page Sort by: Featured View CIVIVI Voltaic Flipper Knife Stainless Steel Handle With Micarta Inlay (3.48" 14C28N Blade) $88.30 Add to cart AEB-L and 14C28N are the best in the high toughness group. Cool! Start comparing steels. We looked at common steels used by popular knife brands to help you select the right material for your blade. in relation to hardness). Divers, sailors, and anglers need knives that will resist corrosion above all else. It would be great if you wrote a basic rundown of cryo treatment of knife steels, whats involved, the effects, interactions with other treatments like tempers, alloys that benefit the most, etc. Softer steel usually forms larger burrs and they are more difficult to deburr. Thank you for the accurate data. and corrosion resistance than the 420HC steel. Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. Cold Steel still uses VG-1 on some knives, and, for the money, it does well. Later, it gets heated and compressed into one ingot. Now that is power planer blades, but the principle stands, less carbon and alloy isnt the best for wood working and Id use a steel like 26C3 (1.25% C .30%Cr) for my hand tools and temper them to around 62 hard and use the best angle for wood shaving, not the best angle for cutting rope. The heat treatment techniques used by the manufacturer as well as the design of the blade itself play a huge role in the ultimate outcome of knife performance! I dipped each in lemon juice and left in open air and tested after 30, 100, and 300 minutes, dipping in lemon juice again each time. The knives are ideal for both indoor and outdoor use. Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. Steels 7Cr and below arent worth your time or money. 14C28N steel also has excellent wear resistance due to its high chromium content. Corrosion Resistance: D2 steel has a higher chromium content than 8Cr13MoV, which makes it better at resisting corrosion and wear. I would suggest adding a second axis to the ratings charts that show the data values that the 0-10 ratings are based on (unnotched charpy impact energy, 1% saltwater , Total cards cut, etc.). 14C28N knives offer excellent corrosion resistance and toughness. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. So what is the best steel for knives? There are still a few things I dont know but we have enough information to make educated guesses where data isnt available. Below shows the results of MagnaCut testing vs other steels where it is labeled as New Steel.. I especially appreciate the geometry/edge retention/toughness comparison with photos. Check out theGiantMouse Vox/Anso ACE Iona Liner Lock Knife at $99, for example. If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. LC 200N is an elite performer, with high hardness, high toughness, and off-the-charts corrosion resistance. Vg10 and cpms45vn same toughness at same hardness ? as you mentioned catra indicates the edge angle as being by far the most important variable. This particular steel grade allows for the highest attainable hardness without. However, many kinds of wood are REALLY tough and very hard on blades. I see very little about cryo outside of journal articles, and I wonder which knifemakers use it. What it is: 14C28N is a Sandvik stainless steel commonly used in razors and kitchen knives. Using controlled furnace heat treating resulted in toughness around 23-28 ft-lbs at 61-62 Rc, while the knifemaker heat treated specimens were 7 ft-lbs or below. If the properties of a knife meet your knife needs and it has the above characteristics, then it qualifies as a quality knife. You can see micrographs of different knife steels to compare their carbides in this article. It mainly made for knife and it high in Chromium for excellent corrosion resistance. Lets talk about the clip-on pocket knife. I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. 2. The consent submitted will only be used for data processing originating from this website. There are a lot of different types of steel out there . Manage Settings Is Vancron SuperClean a good choice for a chef knife? While higher hardness does lead to improved edge retention the bigger reason to have higher hardness is for resisting edge deformation. how much more can you bend/pry with it? Im a layman trying to understand what makes the best steel for my use. Five years ago, S30V had a premium price. I can also say from personal experience that marine grade plywood will chaw up your saw blade and battery a lot quicker than standard plywood, but that probably says more about the glue that was used than the wood. Its found on a large number of traditional-style folders. CRKT and Spyderco use BD1. And below shows a chart of carbide hardness, the equation we created to predict edge retention based on edge angle, hardness, and carbide volumes, and then the chart showing the good correlation: TCC (mm) = -157 + 15.8*Hardness (Rc) 17.8*EdgeAngle() + 11.2*CrC(%) + 14.6*CrVC(%) + 26.2*MC(%) + 9.5*M6C(%) + 20.9*MN(%) + 19.4*CrN(%). In a pocket knife the total amount of steel is rather small. Larrin, thank you for this. REX 121 is a powder steel produced by Crucible. Is that regression line (or other trend line?) You will get an ultra-sharp edge with 14C28N knives. Even premium steels can have poor performance with poor heat treatment. rust resistance.Best of all most knives made from this steel can be had for well under $75.In my opinion Sandvik 14c28n is a better overall steel than that of Aus8,420hc,or ANY of the . 2. The best knife for you should meet your needs and fit your budget. Any idea where it would be on the hardness and toughness scales? 14C28N. Crucible intends SPY27 to be good all-around knife steel. If you want to learn more about a specific steel, you can click it in the sorted listings below. The hardenable grade of titanium (Beta C Titanium) reaches up to 45 or so rc. Looks like there is no reason to us it over 420HC. However, it can be somewhat complicated because an edge can dull from many causes wear, micro-chipping, deformation, or corrosion. 14C28N is offered on midprice knives and is one of the better steels on a dollar-for-dollar basis. Or, is this perhaps a historically useful practice that made sense on softer/less tough steels, but would make less sense on some newer steels that can be used at higher hardness and thus higher edge stability? A few steels have been added since such as MagnaCut and M398. I always thought VG10 to be way more chippy/less tough compared cpms45vn. 20? CPM-REX 121 and Maxamet are both in this category. The value being slightly different doesnt mean its an outlier or measurement error. It mainly made for knife and it high in Chromium for excellent corrosion resistance. It does have chromium but is not as sufficient as required to be a type of stainless steel. Tough steel can handle impacts without gross chipping or a tip breaking off. 1095 stains easily and thus is often coated, especially in fixed blades. I would also suggest adding a hardness rating to the ratings tables that currently include toughness, edge retention, and corrosion resistance ratings.
