At the San Diego comic fest (not comic con) a couple of years ago I met an artist and he raved about the Blackwing pencil. The pencil has a big square eraser on top that can be replaced. He felt that the pencil drew smoother and made a better line for drawings. Researching it I found they are the Palomino Blackwing pencils. They sell for $22.95 a box. You want the ones with the white eraser not the Blackwing 602 or the pearls, both of which have a harder lead (graphite). On the other hand Mark Crilley (he does drawing videos on YouTube) uses a plain old Dixon Ticonderoga number two pencil. They sell for $15.02 for a block of 96 pencils.
Don’t use a pencil that has been sharpened down so much that it cramps your hand to draw with it. Get a pencil extender or a new pencil. With a Blackwing you have to saw the eraser off to use a pencil extender, not a big deal.
Me, I use ordinary mechanical pencils. Either 0.7 or 0.5 mm leads.
What is the worlds best pencil? What ever is in your hand and your drawing with it. Whether you found the pencil on the ground or paid big dollars for it, if you’re using it then it’s the best. It took me to long to figure that out.
