They are used on technical drawings where they clean better than standard erasers. Soft vinyl erasers are used for precision erasing because they can smear large areas. The motor rotates the eraser uniformly, erasing the surface with much less damage than with the hand. An electric eraser is an eraser fastened to a rotor of a small electric motor. In other regards, it works very similarly to the kneaded eraser. Because of how it works, it does not smudge or damage work in progress. “Poster putty” looks like a kneading eraser, but it has much stronger lifting strength and erases the surface by lifting graphite from it. They cannot erase larger areas because they deform while rubbing. Kneaded eraser can be shaped into a fine point to erase small details it can be shaped into a larger surface and work as a stamp, and it can work as a blotter to lighten a darker area covered with graphite. From the iconic Pink Pearl eraser and eraser caps used by the youngest child, to dust-free vinyl, plastic, stick, gum, soap. Still, it loses its efficacy and resilience because the particles that it erases stay inside it. Whether your pencil eraser sits on your desk, drawing board, drafting table, or tucks into your backpack, pencil case, or day planner, it's a simple yet indispensable drawing and writing tool. It does not leave behind eraser residue like an art gum eraser because it lasts longer. “Kneaded eraser,” or “putty rubber,” removes graphite or charcoal from a surface by absorbing it. The only problem is (as with old erasers) that they crumble while doing so, and their residue has to be removed. “Art gum erasers” are made of soft, coarse rubber and are excellent for erasing larger areas because they don’t damage the paper. Today we have erasers of different types, not just shapes. Novelty erasers, modeled as other objects or figurines, are often made from hard vinyl that does not erase too well. Barrel or click erasers are built like mechanical pens with an eraser as a core instead of lead. Most common erasers are in block form or placed at the pencil's end for quick and easy use. Hymen Lipman patented attaching an eraser to the end of a pencil, but he later lost the license. This process made rubber more durable and made the eraser a household item. Lucy had just rubbed out the city and forest she had just drawn.The solution to that problem came in 1839 when inventor Charles Goodyear invented the method of curing rubber - vulcanization. He found himself on a desk of a nine year old girl called Lucy and in her right hand was an eraser. He could not see Eraser anywhere but before he turned around the tree had been rubbed out and so had he. So he went back to the forest and hid behind an apple tree. But Pencil couldn’t do anything because then he would be rubbed out. He found out what an Eraser was when someone screamed and Pencil raced over and hid behind a house with one level. Then the eraser started to jump over to the unnamed city. Then an Eraser fell into the world, but Pencil didn’t know anything about an Eraser. He drew lions, giraffes, zebras, birds, bears, wolves, fish, possums, kangaroos, elephants, lizards, crocodiles, ducks, monkeys, frogs, foxes, snakes and tigers. After he had drawn all the trees he moved on to the animals. There was all different kinds and types of trees like tall, small, apple trees, gumtrees, pear trees, pine trees, eucalyptus trees, magnolia trees and banana trees. He went five minutes away from the city and started to draw trees and animals. But he couldn’t put animals like lions and birds and animals like that in the city. He drew women and men with their pets too. He drew girls and boys holding their pets. He said to himself, “I need to draw living things for my city”. Then an apple dropped on Pencil’s head and he thought of something. He sat himself down on the soft, green grass. So he decided to draw a hill with an apple tree in the centre of the hill. By the way Pencil was really tired and needed a rest. So after about three, four hours he drew a whole city but he didn’t know what to call it. The building was coloured white, remember. So where were we, oh yes Pencil was drawing a building with four windows on each level and there was six levels. There where six levels and your probably guessing that is white too? Well guess what your right. He started to draw a building with four windows on each level. He first drew a house with two levels and it was white since he wasn’t a coloured pencil. So Pencil thought he would draw something in the west bit of the white world. It was a world with nothing, I mean nothing. In about Spring an ordinary pencil fell into a not so ordinary world.
