It may be hardened steel (carbon) or it may have harder metals joined to it (tungsten carbide) or it may be coated in the hardest of materials- diamond dust.
The steel blade of a knife will hold a sharp cutting edge.
A hatchet is typically made of a metal blade (usually steel) and a wooden handle. The blade is designed for chopping and cutting, while the handle provides a comfortable grip for the user.
An instrument with a thin bade made of steel and having a sharp edge for cutting? This is a knife. Care must be taken when handling said knife.
It depends on what blade is in the mounts. A traditionally forged Blade or a Murata-To (late 19th/ early 20th. century oil quenched blade made of European Steel) will have more power than a simple machine made blade that is simply stamped out of milled steel. A lot of Kyu Gunto also have ancestral blades. Of course there are also dress sabers known as Shikito which have thin chrome plated machine made blades. These weren't made for combat.
It is made of metal really.
Iron or steel can be cut by using:hydraulic sheers (like a powerful paper cutter)a saw blade made from a harder allow of steellaser cuttingabrasive cuttinghydraulic cutting (just water or with abrasives)grindingacetylene (or other gas mixture) cutting torchesthermal lances
It is called a Kerf
A knife is conductible as the blade is made of steel.
A good quality jigsaw will cut almost any material with the correct blade. Although I have 3 jigsaws my favourite is the Bosch1578AVS that I've had over 30 years. I still use it 3-4 times a week to cut wood of different kinds, plexiglass and steel. The steel cutting blade is like a very fine hacksaw blade with 24 teeth per inch. An average wood cutting blade will have about 8 teeth per inch.
Concrete cutting blades are typically made from a combination of steel and diamond segments. The steel provides strength and support, while the diamond segments, often embedded in the blade's edge, provide the cutting power due to their hardness and durability. Some blades may also incorporate other materials, such as carbide, to enhance performance for specific applications. Overall, the composition ensures efficient cutting through tough concrete and masonry materials.
Steel cutting tools that are hardened by tempering them can cut softer, untempered steel. Steel that is high in carbon content can be made tougher than low-carbon steel.
