Toughness is the resistance to chipping or breaking. Most low alloy tool steels and carbon steels also have fine carbide structures without powder metallurgy processing. The studies confirmed that the primary controlling factors are hardness of the steel, volume of carbides, and hardness of the carbides. Therefore, you cannot purchase the knife for use in corrosive environments. So hard vanadium carbides means you get more edge retention for a given amount of carbide. The reason is because sharpening and edge geometry will also greatly control properties. VG-1 is a non-powder steel made by Japanese specialty steelmaker Takefu. The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. LC200N at least it has some vanadium over the 420hc.

In fact, its not technically a steel at all, as it uses titanium and nickel. 14C28N VS Steel. Not every wood is soft pine. 14C28N knives are better than D2 knives in corrosion resistance. Carbon steels are those that have primarily carbon added to them with some Mn or Si as well. Im looking forward to seeing if it does as well in full production. 2. Carpenter produces this powder steel. If you look at the chart you may notice that at high toughness levels if you increase edge retention by only a relatively small amount you get very big drops in toughness. This is basically a retrofit of a very old steel, adding more carbon to the recipe of 420 (hence the HC for high carbon). 14C28N and D2 steel are not the same. Theres also a line of green triangles a bit below that.

On the other hand the professional performing blade steels sharpen to a razor edge and hold the edge for an extended use. Advantages: Toughness, edge retention. This isnt exactly how steel works; different properties are difficult to increase without affecting something else. The maximum edge retention available in this group is not particularly high because most of the wear resistance comes from iron carbide, also called cementite, which is the softest of the different carbide types. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. This is an old high-carbon (non-stainless) steel. I was the heat treater, but after HT to only 58-59 hardness the blades went to the surface grinders for finishing and I remember them going into the packing boxes with mirror polished edges. 420HC, 420, and 5160 all offer off-the-charts toughness.
