When it's put like that the amount of energy in your hands is brought home. Then think of it concentrated on the thin edge of a cutting disc or saw and look at the damage it can do in the blink of an eye...Re the power of grinders, drills etc.
A 4.5 inch grinder has an 800w motor or thereabouts, that's 1 horsepower, a 7 or 9 inch grinder has somewhere between 2000w and 2400w . That's 2.5 to 3 horsepower.
To put this in perspective I read somewhere that competitors in the world's strongest man can keep up with a 1hp electric motor for about 30 seconds. Food for thought....
