well if you ask me they are nail tools a fingernail and a penny to me.
nail, penny, your fingernail, or other rocks
When you scratch a mineral with a penny, nail, and your fingernail, you are testing the mineral's hardness. The ability to scratch or be scratched by certain materials helps determine the mineral's hardness on the Mohs scale of mineral hardness.
The hardness of a mineral is determined by scratching it with materials of known hardness, such as a fingernail, a copper penny, a steel nail, or a piece of glass. The mineral is assigned a hardness value based on which material can scratch it. This is known as the Mohs scale of hardness.
La uña = the fingernail or toenail El clavo = the nail (carpentry)
Cut your fingernail then you can use the piont of something then you can get to your fingernail easiley.
An 8 penny nail (abbreviated as 8d) is 2.5 inches in length. A 10 penny nail (10d) is 3 inches in length.
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

It means you have injured a fingernail.
The epithelial tissue under the fingernail is called the nail bed. It is responsible for producing new nail cells and helping to anchor the nail in place on the fingertip.
