This alloy is a chromium-nickel-aluminum precipitation hardening stainless steel with good edge retention. Great corrosion resistance generally means a high chromium content, and this means knives made with this steel will be a little harder to sharpen than blades with a lower chromium content. | 54-56 |\n| 154 CM | Originally designed for jet engine fan blades, it is the precursor to the Japanese made ATS-34 . 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. | 58-62 |\n| 420 | A hard, strong blade steel. 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. | 49-53 |\n| 420 HC | A high carbon version of 420 steel, this steel combines the excellent wear resistance of high carbon alloys with the corrosion resistance of chromium stainless steels. The high carbon content makes this steel harder to resharpen, but the tradeoff is better edge holding properties. | 58 |\n| 440 A | A high carbon stainless steel, used in many production knives. A good balance of edge retention, easy resharpening and corrosion resistance. | 55-57 |\n| 440 C | A high chromium stainless steel which exhibits an excellent balance of hardness and corrosion resistance. This steel takes a nice edge, and is fairly easy to sharpen even for a novice. | 58-60 |\n| 1095 | This is a plain carbon steel, which means it has low resistance to corrosion, and low to medium edge retention. 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. | 56-58 |\n| 5150 | A medium carbon, low alloy steel that hardens well. This steel is ideally suited to blades with a very thick cross-section such as tomahawks and axes. Extremely tough and impact resistant, this steel is most often used on blades which are hafted and/or thrown. | 55-60 |\n| 8Cr13MoV | A medium-grade stainless steel, similar in many properties to the AUS 8 series. Good edge holding properties, and easy to sharpen. Decent corrosion resistance. | 58-60 |\n\n\n| Aogami Super\u003Cbr>Blue | Aogami Super Blue steel is produced by Hitachi Metals for tools and knives. Super Blue is the highest grade blue steel and contains up to 1-1/2% carbon for wear resistance and chrome to elevate hardness and improve edge holding and corrosion resistance. Classified as exotic steel by cutlery standards, it has a loyal following with custom kitchen knifemakers looking for superior cutting performance. Aogami Super Blue is a high-performance, high-carbon steel and isnot stainless. It requires proper and diligent maintenance to keep it corrosionfree. Often laminated between softer steels for use in knives. | 60-61 |\n| --- | --- | --- |\n| ATS-34 | A very high carbon, chromium stainless steel with additional amounts of molybdenum. This steel has good edge holding properties and high corrosion resistance, but is more difficult to resharpen than lower chromium steels. | 60-61 |\n| AUS 6A | A medium to high carbon stainless steel, this steel holds a good edge and is particularly well suited for heavy, long blades that are subjected to a lot of stress while chopping and hacking. It has good edge retention, and is fairly easy toresharpen with decent corrosion resistance. | 55-57 |\n| AUS 8 | A Japanese stainless steel, with superb toughness and good edge holding capabilities. This steel is fairly easy to sharpen and generally low cost with great corrosion resistance. | 57-58 |\n| AUS 8A | A high carbon, low chromium stainless steel-a good compromise between toughness and strength, edge holding a","cbCaiu02ElZCdI9z","https://ap.wps.com/l/cbCaiu02ElZCdI9z","pdf",41863,"English","# Knife Steels - Steel Type Characteristics\n## Austenitic/Chromium-Nickel Stainless Steels\n## Japanese Stainless Steels (AUS/Aogami)\n## Carbon and Semi-Stainless Tool Steels\n## Powdered/Stainless Specialty Steels\n## Composite Pattern Steels (Damascus)","[{\"question\":\"How does chromium content generally affect sharpenability for knife steels?\",\"answer\":\"Higher chromium content usually improves corrosion resistance, but knives made with higher-chromium steels are typically a little harder to sharpen than blades with lower chromium content.\"},{\"question\":\"Which steels are described as easy to sharpen versus harder to resharpen?\",\"answer\":\"The chart describes several steels as fairly easy to resharpen (e.g., 154CM, 420, 440A, 440C, 1095, AUS 8).
