When was the diamond blade invented?
1926
1926 – Felker Diamond Segmented Blade
Felker invented the diamond segmented blade and it was first used in manufacturing, specifically to cut raw materials used in electrical components.
Why is it called a diamond blade?
Simply put it means that as more diamond is added to the segment more horsepower is needed to make the blade cut. In practical terms this means that blades for high horsepower saws will have more diamond in the segment.
Who invented the concrete saw?

Are there real diamonds on a diamond blade?
The short answer is no, the diamonds used in diamond blades are not real. The diamond crystals that are used in the construction of the diamond blade segments are artificial and are made with the purpose of being stronger than natural diamonds.
What can cut diamond?
Diamond manufacturers cut a groove in the diamond with a laser or saw, and then split the diamond with a steel blade. Sawing is the use of a diamond saw or laser to cut the diamond rough into separate pieces. Unlike cleaving, this step does not involve cleavage planes. This step gives diamonds their initial shape.
How sharp is a diamond blade?
They’re extremely sharp, and they hold their razor edge exceedingly well (which is kinda the point of coating them in diamond). It could be sharp. There’s no absolute reason it would have to be sharp other than that swords are supposed to be sharp. You can buy diamond coated razor blades.
Who invented the electric saw?
A 5-Minute Circular Saw History
Edmond Michel developed the first electric handsaw in 1923.
Why is it called a worm drive saw?
What is a Worm drive saw? A worm drive saw has the motor attached at the rear. This is very powerful and its power is driven through two gears each set at 90 degrees. This setting implies that the engine produces more torque but less Rotation Per Minute (RPM) of about 4,500.
When was the wet saw invented?
1926
History of Wet Cutting
In 1926, a blade was invented that could cut stone, brick, and concrete masonry materials. The cutting or grinding was possible by using diamond grit or chips embedded in a metal matrix creating the segment.
What is the sharpest knife in the world?
Obsidian knife blades
Obsidian knife blades: overkill for slicing your sandwich. The thinnest blades are three nanometres wide at the edge – 10 times sharper than a razor blade. These are made by flaking a long, thin sliver from a core of obsidian (volcanic glass).
