But nowadays it is made up of a mixture of graphite powder and clay. Note:In early years, lead pencil was made up of graphite powder only. Thus, the correct answer is option (B) false. Thus, the statement ‘lead pencil is made up of lead metal’ is false. So, lead pencil is made up of graphite powder which is an allotrope of carbon and not of lead metal. The core of lead pencil is made up of thin graphite which is enclosed in a shell of some other material which is made up of wood, plastic or recycled paper. The black or grey marks are resistant to chemicals, moisture and natural aging. The black or grey marks can be erased easily using an eraser. The graphite pencil leaves behind a black or grey marks when written with it. The lead pencil is actually a graphite pencil. The core of the lead pencil is made up of a mixture of graphite powder and clay. We know that carbon has three allotropes: diamond, graphite and fullerene. The core is made up of an allotrope of carbon. The casing prevents the core from being broken down. The pencil consists of a solid core inside a protective casing. We know that pencil is used for drawing and writing purposes.

So, while there isn't any one right answer for "what is the best mechanical pencil?," you can find the world's best writing tools on Goldspot Pens and find one (or five) that best fit your needs. Much like a painter has an assortment of brushes to fill a canvas, a creative artist will employ an assortment of pencils is varying lead hardnesses and diameters to create a piece. Whether you're drafting the floor plans to an office building or casually sketching a city skyline, there's an ideal pencil for you. By carefully selecting the lead diameter and lead hardness, the writer/artist can fine tune their pencil to best suit their needs. Similar to the range of nib options available with fountain pens, mechanical pencils provide the user with a tool tailored to their work. Finding the right mechanical pencil for you Mechanical pencils are much more pocket friendly, as they typically have a pocket clip and the lead can be retracted to hide inside the pencil when not in use. Instead of discarding the pencil when it becomes too small to use, each stick of mechanical pencil lead can be used almost all the way until the mechanism can no longer hold the graphite. Mechanical pencils under 0.7mm in lead diameter deliver a consistent line without needing a sharpener. In contrast to the consumable wood pencil, the mechanical pencil can write forever as long as the lead is replaced. Also, without using a pocket protector or pencil cap, putting a sharpened pencil in your pocket can lead to a hole in your favorite shirt or bodily harm if you accidently poke yourself with the tip. Thus, the user cannot effectively use 100% of the pencil, disposing of the stub when it becomes too small. At the end, a woodcase pencil can be sharpened to the point (pun intended) where the pencil is too short to write comfortably. Each time you sharpen a wood pencil, you shave away a piece of your writing tool. Woodcase pencils are 100% consumable and disposable. Why Choose a Mechanical Pencil over a Typical Woodcase Pencil? An artist may use the lead on the side of the point to fill in large areas of value. Although the lead is measured by its diameter, the point is sharpened and will require a sharpener to control the line thickness. Leads above 2mm are usually considered "sketch" mechanical pencils that clutch the larger piece of lead. In the fountain pen world, these would be your "medium" point sizes available on most pens. Leads between 0.9mm and 1.4mm are suitable for general purpose writing and sketching. Thinner leads are ideal for those who have small, neat handwriting. The lines will appear lighter on the paper and are easier to erase. Thinner leads under 0.7mm are best suited for light, technical drawings, drafts, and fine details. While it is possible to use different lead hardnesses (2B, HB, or 2H, for example) in the same lead diameter, it is not possible to switch a different lead diameter (like putting a 0.9mm in a 0.5mm pencil) in a mechanical pencil. This means that a 0.7mm mechanical pencil only accepts 0.7mm diameter lead. Mechanical pencil mechanisms are fixed for the type of lead they accept. Depending on how you intend on using the pencil, the lead diameter plays a major role in selecting a mechanical pencil, moreso than lead hardness.
