Most knives have a rockwell hardness of 54-62. this is for metals. minerals are considered ceramics and therefore should have more hardness. It really depends ont he pressure applied. With enogh pressure any knife can scratch any mineral.
A mineral that will scratch with a window glass but not with a knife blade is a mineral with a hardness between 5.5 and 6.5 on the Mohs scale, such as orthoclase or peridot.
The scratch test can help distinguish gypsum from quartz. Gypsum is a soft mineral, so it can be easily scratched with a fingernail or with a knife blade. Quartz, on the other hand, is much harder and cannot be scratched with a knife blade.
The Chidori and Lightning Blade are both techniques used in the Naruto series that involve channeling lightning chakra. The Chidori is a high-speed jab, while the Lightning Blade is an enhanced version with more power and speed. In terms of toughness, the Lightning Blade is considered more powerful and challenging to master due to its increased intensity and precision.
Jade is a green mineral that is sometimes used to make cutting devices, such as knives or blades. Its toughness and ability to hold a sharp edge make it a popular choice for traditional tools in some cultures.
The Mohs Scale of Hardness was developed by German mineralogist Friedrich Mohs. Higher numbers are assigned to minerals that scratch the harder common objects on the scale. i. 10- Diamond ii. 9- Corundum iii. 8- Topaz iv. 7- Quartz v. 6.5- Streak Plate vi. 6- Orthoclase Feldspar vii. 5.5- Glass, Masonry Nail, Knife Blade viii. 5- Apatite ix. 4.5- Wire (iron) nail x. 4- Flourite xi. 3.5- Brass (wood screw, washer) xii. 3- Calcite, Copper coin (penny) xiii. 2.5- Fingernail xiv. 2- Gypsum xv. 1- TalcMoh's hardness test
The hardness of a material that scratches a knife blade would typically be higher than the hardness of the knife blade itself. This implies that the material is able to physically deform or remove material from the knife blade due to its greater hardness. This property is commonly assessed using the Mohs scale of mineral hardness.
Mineral that can be scratched with a knife blade or a window glass is gypsum.
a diamond
A mineral that will scratch with a window glass but not with a knife blade is a mineral with a hardness between 5.5 and 6.5 on the Mohs scale, such as orthoclase or peridot.
Yes, knife scratches (steak or otherwise) can show up on melamine. Melamine is fairly hard, but not that hard compared to a knife blade.
Quartz is a mineral. It has a hardness of 7 on Mohs Scale of Hardness; thus, it scratches glass but it is not scratched by a masonry nail or knife blade. It does not have any cleavage, it only fractures, and it can have conchoidal fracture (similar to glass). It is also a light-colored nonmetallic mineral with a greasy luster. It can be colorless, white, gray, or other colors. Other distinctive mineral proprieties include its hexagonal prisms, pyramidal structure, and that it can be transparent or translucent.

An axe could be considered a blade.
It means to turn your oar so the blade is parallel to the surface of the water
