A steel and carbon compound that is much stronger than regular steel.
Spending time in your car.
An epoxy and carbon compound that is much stronger than regular steel.
A carbon and fiber compound that is much stronger than regular steel.
What is an abrasive blade?
A rude blade that just does not get along with other blades
A blade made from fine particles like the surface of sandpaper bonded together to form a blade or grinder wheel.
Small scissor like teeth are needed when
Thin material that splinters easily is being cut, such as the veneer layer of plywood. Smaller teeth reduce splintering
You cannot get a hold of Edward Scissorhands to do your cutting. Please read and understand the other option, that is what you need to know.
Carbide is better than "high speed steel" because (it)
Has a stronger chemical bond that allows the microscopic edge to stay sharper through more wood cutting.
Is good for lower speeds
Is better for higher speeds
the "high speed steel" chemical bond weakens at a lower heat than carbide, causing the cutter to become dull easier.

A demolition saw is...
...a liquid fuel or electric saw that wears its way through hard heavy materials such as concrete by rubbing through it at high speed with and abrasive blade.
... a diamond blade that can be used in a demolition saw. This is true, but not the answer here.
... an abrasive blade is much cheaper than a diamond blade, but cuts slower, makes more dust, and wears out quickly. This is true, but not the answer here.
