A bevel is an angled, sloping edge - one which is not at a 90 degree angle.
A helicoid. The outer edge is a helix but since it is a plane, not a line, it becomes a helicoid.
A knife edge.
The intersection of two planes or faces makes an edge.
Two planes intersect (not interscept) at an edge (or a line).

Operation Sharp Edge happened in 1990.
"Projecting" in this case means "sticking out." So a sharp projecting edge is a sharp edge that sticks out.
Yes, an axe is a simple machine. The axehead is called a wedge, or two incline planes put together to make a sharp edge.
In geometry an inclined plane would be infinite and so would not have and edge. And edge does not need an inclined plane. In school mechanics (physics or mathematics), an inclined plane is often used to study forces. But in almost all cases the edges of the inclined plane are "out-of-bounds".
A knife edge.
Any mineral that can be broken (cleaved) at a sharp angle can have a sharp edge. Substances like Flint are good examples
