I have small screwdrivers that weigh about one ounce.
it does not weigh a pound too small

Some can weigh as little as 1.5 oz.
Not very much as they are very small.
Depends on size
About 6.5kg
10000
as much as 3-5 lbs
I would say anywhere from 1 to 20 lbs but i don't know for sure.
About 5 litres
350, to 400lbs.
It depends on the screwdriver. Only a really little one would weigh 3 ounces...but I guess you could make a great big screwdriver with a real long shank that weighs three pounds.
