1095, a popular high-carbon steel for knives; it is harder but more brittle than lower-carbon steels such as 1055, 1060, 1070, and 1080. It has a carbon content of 0.90-1.03% [7] Many older pocket knives and kitchen knives were made of 1095. With a good heat treat, the high carbon 1095 and O-1 tool steels can make excellent knives.
A blade made from low carbon or mild steel would be inexpensive to produce and of poor quality. A low carbon blade would be very hard to break, but would bend easily and be too soft to hold an edge. High carbon (or high alloy, in some listings) can take a much higher hardness but must be tempered carefully after heat treatment to avoid brittleness.
A cold work steel used for gauges, cutting tools, woodworking tools and knives. It can be hardened to 66 HRC, typically used at 61-63 HRC. Also sold as 1.2842 and 90MnCrV8. [9] O6: 1.45% C, 1.0% Mn, 1.0% Si, 0.3% Mo: A cold work graphitic steel with outstanding resistance to metal-to-metal sliding wear and galling.
An image of a modern pattern welded knife blade, showing the dramatic patterning on the side below, and the layering of the steel in the spine above. Acid etching darkens the 1080 plain carbon steel more than it does the 15N20 low alloy nickel steel, producing alternating bands of light and dark on the surface.
Steel that has a carbon content between the high and low carbon steel is called bu-kera, which is often re-smelted with the pig iron to make saga-hagane, containing roughly 0.7% carbon. Most of the intermediate-carbon steel, wrought iron and resmelted steel will be sold for making other items, like tools and knives, and only the best pieces of ...
Polishing stainless steel can also increase its sanitary benefits. The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer.

For example, a butcher steel is a round file with the teeth running the long way, while a packer steel (used in the meat packer's industry) is a smooth, polished steel rod designed for straightening the turned edge of a knife, [11] and is also useful for burnishing a newly finished edge. Because steels have a small diameter they exert high ...
