Lead is a metal but pencils do not contain lead. The gray material in pencils is graphite which is a form of carbon. In most pencils a metal ring binds the eraser to the wooden shaft. That could be detected but the graphite would not. A mechanical pencil made of metal or having some metal parts could be detected but not because of the graphite contained therein.
yes
Stainless steel. I did an experiment about magnets and pencil sharpener blades are steel, which is a magnetic metal. (It cannot be aluminum, as it is not magnetic)
screws, handle, wheel and axel, blades, metal, gears and levers
usually pencil sharpeners are made of plastic and metal.
it is still used today by just sharpening it by hand with a plastic sharpener with a metal blade it in and some of them now are electric and can just put the pencil in the hole and it sharpens by using electricity

it was used by hand,turning the pencil left or right sharpening the pencil up against the blade inside the plastic or metal border
A pencil sharpener uses a blade that rotates around the pencil shaving the wood back from the lead into a point so that it makes a point. A knife sharpener works by using a chunk of metal harder than the knife to shave metal off of the knife into a point to make it sharp.
Kellyco Metal Detectors was created in 1955.
There are many great stores that sell quality white metal detectors. These include Regton, OKM Metal Detectors, Kelly Co Detectors, as well as retailers on the Amazon website.
they detect metal
Yes, you can wear metal blades.
Minelab Metal Detectors currently makes their modern metal detectors rechargeable which is a lot better for the environment. The ones that take batteries die easier anyways.
