YES! Apart from wax pencils used for marking glass etc, and wax pencils used in colouring a drawing.
And I'd forgotten the slate pencils I used at school. And since they Seem to be missing from the Wikipedia article on pencils, here a few comments.
[A slate pencil was used in conjunction with a slate board. [I use imperial measures as metric seems incongruous in this context.] The board was, from ancient memory, [must do some research] a piece of smooth slate, about 8 inches long and 6 inches wide. Set into a slender protective wooden frame. The pencil was also a piece of slate formed into a rod about the size of a normal pencil, but perhaps 5 inches long. This was wrapped in paper and could be sharpened in a normal pencil sharpener.
This was used for children practicing writing. The marks made on the slate surface contrasted well with the background and could be easily removed with a soft cloth or a wet wiping. ]
What else can I help you with?
Who is theory was that the earth is round not flat?
Since the determination of the fact that Earth is spherical as opposed to flat, all scientists (after a short lag period) have accepted that it is so.
What are flat screwdrivers?
It's used to work with flat screws, which,frankly are really a pain. I'm so glad we now have Robertson and phillips screws.
Why do flat maps have distortions?
because there has to be some kind of distortion of earths spherical shape
Is the question the earth is flat a testable hypothesis?
Yes, it is. Satellite imaging will negate the hypothesis and prove that Earth is round, not flat.
What is vas water?
Flat water
Why are carpenter pencils flat?
Carpenter pencils are flat because they are designed to prevent them from rolling away when placed on an inclined surface, making them more convenient and practical for carpenters and other tradespeople to use while working.
How are carpenter pencils better than regular pencils?
Carpenter pencils are better than regular pencils for a variety of reasons. The lead in carpenter pencils are strong and are able to withstand the stress of marking on hard surfaces. Carpenter pencils are also able to survive a construction environment such as being put into a bag accompanied by heavy tools. These reasons are why carpenter pencils are better than regular pencils.
Why are carpenters pencils flat instead of round?
Carpenter's pencils are flat instead of round because they are less likely to roll away when placed on a slanted surface, making them more practical and convenient for carpentry work.

Why are construction pencils flat?
Construction pencils are flat because they are less likely to roll off surfaces, making them easier to handle and less likely to get lost on a job site.
What mineral are that form flat soft flakes?
Talk Graphite
Why is a carpenter's pencil flat?
So it won't roll away while you're working.
What is the cleavage of graphite?
graphite breaks by cleavage because the bonds between its atoms are less strong in directions
How many directions of cleavage does graphite have?
Graphite has one direction of cleavage, which means it cleaves easily along one plane, resulting in thin sheets. This property is due to the layered structure of graphite, where atoms are arranged in flat sheets held together by weak forces.
Chemical formula of graphite?
Graphite is a form of carbon (C12) in which the atoms are generally arranged in flat layers of hexagonal formation, thus giving it its softness. Diamond is another form of carbon, this time with the atoms linked in a rigid, tetrahedral arrangement which affords the crystal its great strength.
Number of adjacent carbon atom in graphite?
In graphite, each carbon atom is bonded to three other carbon atoms in a hexagonal lattice structure. This creates a 2D network of interconnected carbon atoms that form layers. Each carbon atom in graphite is adjacent to three other carbon atoms within the same layer.
What is graphite' s chemical formula?
Graphite is just an allotrope of the element carbon, in that it is carbon in a different form. Graphite exists in a hexagonal planar structure which allows sheets of graphite to slide over each other easily which is what you see when you write; it is also used as a lubricant (though not in a vacuum) The allotropes of Carbon include diamond, graphite and fullerenes.
