The fact that there are substances which are harder than steel.
Calcite scratching a copper coin is harder because calcite has a higher Mohs hardness scale rating than copper. Steel files can scratch penknife blades because steel is harder than the blade material, which is usually softer.
The way I understand it is the process of folding the steel or pattern welding causes a laminated type steal blade that is more flexible than a solid blade of the same steel. When it is folded it is not molten together but bonded. If it was molten together it would not have the characteristics of a laminated blade but a solid piece as if smelted. Think of a laminated piece of wood against a solid piece and you can understand the difference in flexibility and overall strength. Like that of a laminated bow. The laminated blade would flex more and be less likely to break, strength is typical of the hardness of the steel as well. So in a way it would be stronger because of flexibility but you have to take into consideration the hardness. I would research into differential hardening techniques used by sword craftsman to learn more. Hope this helps. Jerrud
The physical property that explains this is hardness. Diamonds are much harder than steel, so a diamond saw can maintain its sharpness and cut through hard materials with less wear and tear than a standard steel saw.
Steel is a conductor of electricity because it contains charged particles that are free to move and carry an electric current. This conductivity property allows electricity to flow through a steel spring.
An Archimedean Screw is typically made of a helical screw blade wrapped around a central shaft. It is commonly constructed from materials such as stainless steel, carbon steel, or plastic, depending on the specific application and environment in which it will be used.
Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.

To fix scratched stainless steel surfaces, you can try using a non-abrasive cleaner or a stainless steel polish. Gently rub the cleaner or polish onto the scratched area in the direction of the grain of the stainless steel. This may help to minimize the appearance of the scratches.
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
no, obsidian is a volcanic glass and would shatter under a strike from a steel blade. DO NOT ATTEMPT THIS, AS YOU WILL DIE OR BE INJURED.
To fix scratched stainless steel surfaces, you can use a stainless steel cleaner and a non-abrasive cloth to gently buff out the scratches. If the scratches are deep, you may need to use a stainless steel polish or a scratch removal product specifically designed for stainless steel.
Steel True, Blade Straight
High carbon steel
Yes, because talc is very soft.
knife
Yes, the steel blade can be cleaned using a bit of soap and water. Rinse and dry the blade straight away and avoid rubbing on the handle. Simple and easy.
