Knife steel edge retention chart
It can be difficult to keep track of all the types of steel used in knives. This year there are a lot of new knives with steel types that many people are not familiar with. I recently ran across a couple of knife steel comparison charts for some of these steel types that I thought I would share with you. Crucible Parts Metallurgy makes several very popular knife steels. It is also easier to machine and polish.
Also, V 10V and V offer huge amounts of wear resistance, if you can get an edge on them in the first place; they are incredibly difficult to machine. Carpenter Steel makes knife steels that are gaining in popularity, especially in Spyderco models.
Carpenter steels are named a little differently than other steels, but it is easy to get used to. Once again, these values are relative to one another.
But you can use this chart by taking an alloy with which you are familiar, such as C stainless, and move up or down the diagram with respect to the desired characteristics of an alloy.
The Best Knife Steel: Knifemakers Weigh In
Bohler Uddeholm Steel is also gaining popularity with new knives coming out this year. Elmax steel is gaining popularity as a super steel because it has lots of edge retention with good toughness. Excellent in salt water. Toughness and edge retention like Elmax. It hardens and tempers to HRC. Here are the toughness results, as measured by Bohler Uddeholm.
The dark blue plotted line is the Rockwell C Hardness measured for each steel tested. Remember the higher HRC rating, the lower the toughness will be.
Then you can make general comparisons between the different steels. Great post! The charts are very helpful.

In recent years, this steel has made a resurgence in the knife industry, offering good blade toughness, edge holding capability and corrosion resistance. Fairly easy to resharpen. This stainless steel is commonly used in knife blades, and offers good corrosion resistance at a low cost.
Decent edge holding capabilities and fairly easy to resharpen, this steel is a good balance of the most desirable traits for knife steel.
The high carbon content makes this steel harder to resharpen, but the tradeoff is better edge holding properties. A good balance of edge retention, easy resharpening and corrosion resistance.
This steel takes a nice edge, and is fairly easy to sharpen even for a novice. The benefit of this steel is it's easy to sharpen, will take an extremely sharp edge and is generally available at a low cost.
This steel is ideally suited to blades with a very thick cross-section such as tomahawks and axes. This steel has good edge holding properties and high corossion resistance, but is more difficult to resharpen than lower chromium steels. It has good edge retention, and is fairly easy to resharpen with decent corrosion resistance. This steel is fairly easy to sharpen and generally low cost with great corrosion resistance.
Easy to sharpen, with decent corrosion resistance. Decent corossion resistance with superior edge retention make this a premium steel for knife blades.Diagram based 2005 monte carlo wiring diagram
This steel is exceptionally tough, and therefore harder to sharpen than most stainless steels. It is a powder made steel with uniform structure and great corrosion resistance.You can click on the column to sort the data accordingly. Contributes: HardnessEdge Retention. Generally with increased levels of carbon you get a harder steel, improved tensile strength, edge retention and overall resistance to wear.
However, if manufacturers go over the top with too much carbon it can make the steel brittle and also increases proneness to corrosion. Contributes: Corrosion Resistance. By adding chromium to the steel it increases the resistance to oxidation and corrosion in general. Chromium is the key driver for carbide formation which lowers brittleness but also adversely impacts edge retention. In addition to improving the resistance to corrosion, chromium also improves hardenability and tensile strength.
Still, every steel is going to corrode if left out in the elements for a prolonged period. Note also that too much chromium can reduce toughness. Contributes: Toughness.
Molybdenum will increase toughness which reduces the liklihood of chipping. It also allows the steel to maintain its strength at high temperatures which helps with how easy a blade is to produce in the factory.
Like chromium it is a driver of carbide formation but is used typically in small relative quantities. Some manufacturers have chosen to add small quantities of Nickel to increase toughness and strength especially at low temperatures which basically limits distortion and cracking during the quenching phase of heat treatment. Many knife makers claim it also reduces corrosion but that is often disputed. Contributes: Toughness, Wear Resistance. Vanadium is another element similar to Molybdenum that promotes carbide formation the hardest of all and it adds wear resisting properties to steels.
Some of the ultra-premium steels contain relatively high levels of vanadium and allow for a super sharp edge. Contributes: Hardness. Adding very small amounts of cobalt can allow for quenching i. It is not a carbide former in itself but certainly does promote the achievement of overall hardness.
Contributes: Hardenability, Strength, Wear Resistance. Another key element which assists with the hot working properties making the knife more stable during quenching. Manganese will contribute to increased hardness as well as tensile strength and resistance to wear and tear.
As with anything that increases hardness, too much and the steel will be too brittle.The materials used to make the blade-steel of Japanese knives, can be classified into two distinct categories.
Carbon steel is made through the process of adding carbon to steel made from iron ore. The mixing of chrome with the steel prevents the material from rusting, thus making it a popular choice in kitchen knife construction.
The steel is very pure, in which it has very little impurities such as phosphorus and sulfur in the steel's make up. The steel does rust easily, however the edge it holds is regarded as one of the best. This steel is very hard and also very tough.
Has great edge retention and is surprisingly easy to sharpen. Typically the steel has an HRC of The metallurgic content is a bit different however. This process allows for a very consistent gran structure in the steel which makes the blade easier to sharpen and very durable. Has a 64HRC. Compared to other types of stainless steals it has a very high hardness and abrasion resistance.
It is known for excellent corrosion resistance, great sharpness and excellent blade functionality. It is difficult to sharpen however, due to the hardness of the material. HRC is from Is a great introduction steel to Japanese knives, in which, it is easy to sharpen, very durable, rust resistant, and is usually reasonably priced.
The cutting quality is similar to that of a shirogami steel.
Which Steel Has the Best Edge Retention? Part 1
Tamahagane : Tamahagane is a traditional type of carbon steel used to make knives and swords in Japan. The carbon steel was made using a tatara blast furnace. Log in Cart 0 Checkout. Home Super Deals! Brands Deals of the day! Japanese Knife Blade Steels. Blade Materials: The materials used to make the blade-steel of Japanese knives, can be classified into two distinct categories.
High Carbon.Based on a poll of Knife Steel Nerds Patreon voting members, we have decided to purchase a small impact tester for knife edges. This will allow us to study the effects of steel, heat treatment, edge geometry, sharpness, etc.Bhoomi 720p download
I can see how these would be popular articles for budding knife enthusiasts as it can be overwhelming to figure out what to look for in a knife purchase. The available datasheets from the steel manufacturers are often missing information on specific toughness, wear resistance, or corrosion resistance tests and when they do have them the tests are typically not comparable between the manufacturers.
So the ratings that are generated by those writing these articles are basing them on their own experience, the reputation of each steel, what limited information is available from the steel manufacturers, and how they feel that morning.
So I did a couple google searches, opened all of the articles in the first 2 or 3 pages, and kept each that had ratings for blade steels.Opnet network simulator
I narrowed down the list to 5 articles that I will be commenting on. I will be criticizing their descriptions of steels and steel properties as well as the ratings that they provide. Some will seem like nitpicking but I have tried to keep my analysis to relatively objective things and to avoid things I think are simply poorly explained.
To understand how I know the approximate properties of different knife steels, you have to read my articles on what controls different knife properties. It is a bit difficult to summarize within this article which already requires many words to evaluate the different rankings. Here are links to learn about a few of them:.Arb kizomba afro instrumental trap dowload
Here is an article about how chipping of edges happens to understand the mechanisms that occur and so how we evaluate different steels based on those mechanisms. And here is an article where I took micrographs of 42 knife steels which has the most up-to-date toughness charts developed for this website. Corrosion resistance of knife steels. Huston begins his article with a relatively meaningless introduction that seems to be for the purpose of linking to his other articles on which knives to buy:.
They are especially critical in survival situations.Best Overall EDC Knife Steel? Petes Conclusion
In fact, there has probably never been a time where you were relieved to not have your knife on you. I had to read that second sentence a couple times before I figured out what he was saying but I have to disagree. I am relatively frequently relieved that I remembered to not bring a knife with me every time I visit an airport or a theme park with metal detectors.
Fortunately I have not encountered any survival situations at either location thus far. Chipping is normally considered part of toughness rather than wear resistance. Too much toughness can lead to a blade easily warped. No, toughness has nothing to do with a blade easily warping.
Which Steel Has the Best Edge Retention? Part 1
He next defines the effect of different alloying elements in steel. For example, he says as anyone does in these kinds of articles that higher carbon means higher hardness. However, how much harder is SV with 2. How can a knife consumer determine that by looking at the steel composition? Now for the actual ratings which I assume is what most people are looking for when they click on one of these articles. Someone who has been around knives a little while and learned a thing or two can see that S90V has higher wear resistance than However, there are still easy things to point out in most of these, first here are the ratings themselves:.
VG is given the same rating as Elmax for edge retention and a higher score for edge retention and wear resistance than S30V; VG is a step below in wear resistance from those steels. S30V is given the lowest rating for toughness, which seems like a stretch. M gets a higher score than Elmax for toughness even though Elmax is tougher.
That seems like enough examples of poor ratings of steel. Knife Blade Materials — by KnifeCenter. The anonymous author starts by giving properties of steel, which are mostly fine though I would write them differently.Keep in mind that the higher the hardness, the harder it is to sharpen the blade.
Take a closer look at what a knife's HRC implies:. Steel resistance to corrosion refers to the resistance to rust and any other damage that can result from the elements including moisture and salt. In this metric, more isn't always better and there is an optimal number depending on your application.
Knives that are high-resistant to corrosion often have a lower edge performance. Edge retention refers to how long the blade will remain sharp as you use it over time. There is no set scale for this metric but we have set a scale of one to ten. Note that as the numbers are higher the greater the edge retention requiring less sharpening.
Blade Steel Reference Chart. Jantz Knife Supply provides a wide selection of blades, from a heavy-duty kitchen knife to a practical pocket knife, for various needs.
Choosing the right steel for your knife depends on how you use your blade and how often. We offer the best materials, allowing you to craft high-quality practical artisan knives and more. Three main factors to consider when choosing blade steels include resistance to corrosion, edge retention, and hardness.
To assist with making a choice, we also offer helpful metrics. Hardness, or HRC, is a metric referring to steel's resistance to heat, stress, and other forces applied to knives. A knife must have an HRC of at least Notify Me! Email me when available Subscribe to this product to receive notification once it become available.
