As most people are familiar with, a medium is a writing medium with a lead-lead nib that has been coated (or etched) with ink. The nib can be black, white, or a variety of other colors. The difference between a medium nib and a fine-fine nib is that the ink is suspended in a solid gel, which makes it much more prone to feathering than a paper with a lead-lead nib.
A pencil, however, is not normally coated or etched. Instead, the tips of the nib are simply cut off, a process of friction. This makes the pencil as “sticky” as a piece of paper that has been folded in half, and the nib doesn’t get all the way in. There is still the possibility that the pencil may feather a bit with ink or water in one direction. If this happens, a pen user can often help to correct the problem by applying pressure to the paper, thus forcing the pencil over the feathering area and causing the feather to gradually disappear.
What is a pencil end?
When a pencil tip is “cut” off, the end portion of the pencil sticks out of the end of the pencil (Figure A). As noted earlier, an ink-containing fountain pen uses a sharp edge that is cut away from the end portion of the tip. But unlike a fountain pen tip that can easily be removed and replaced in the same way, the pencil end will need to be removed before the ink starts to run out.
The end (or stub tip) of a pencil is normally attached to the tip with plastic or rubber washers (Figure B). This helps to maintain the pencil end in a straight position and keep it clean. The stub tip is usually very shallow at the bottom because the ink does not generally run very deeply.
The end of a pencil is usually attached to a long, cylindrical piece of metal called a spool that is bent to the appropriate length of the pencil. If the tip is too short or too long, it cannot fully support the weight of the tip and the tip will break when drawing.
How can I get the ideal nib height?
The ideal nib width should be around 7–8 mm in diameter, which is around the same distance as a standard 3 mm-wide nib (see Figure C). It is not uncommon for manufacturers to set a nib width as low as 5 mm, to give a nice balance of writing sensation for the user without compromising the overall
