The force required to break the skin depends on how sharp the sharp blade is and where on the body you are cutting, also on the age of the person being cut.
area of the edge of the blade is smaller for a sharp knife. so for the same force the pressure under the blade will be greater and smaller force required to give the same pressure.

A knife blade is considered a wedge, which is a type of simple machine. When force is applied to the knife blade, it allows for the cutting of materials by separating them along the sharp edge.
In physics pressure is defined as P=F/A where P=Pressure F=Force A=Area that is, if F is constant, lower the area (on which force is applied) higher the pressure that area) that's why knife blade got a sharp (low area) point so that it can maximise the pressure on the object that will be cut.
The process of using a knife-like blade to separate materials involves applying force to the blade to cut through the material along a specific path. The sharp edge of the blade creates a cutting force that splits the material apart. The blade should be guided along the desired cutting path with steady pressure for an effective separation.
A razor blade is considered a wedge because it has two inclined planes that come together to form a sharp edge, which concentrates force to easily cut through materials. The thin, triangular shape of the blade allows it to penetrate and separate objects effectively.
a Reverse blade sword is a alternate or a katana blade with the sharp part curved inward and the flat dull part as the original sharp edge
A sharp one.
they are as sharp as a saw blade
To determine if skates are sharp, you can carefully run your finger along the edge of the blade. If the blade feels smooth and sharp, it is likely sharp. Be cautious to avoid cutting yourself. Alternatively, you can also visually inspect the blade for any dull or uneven areas.
Replace it with a sharp scalpel blade
Diamond blade is very sharp, and not only that, it also hard as it made of fabricated diamond on teeth of the blade. And it depends on the type of blade you use. They make some shape of the teeth for special job.
