A drafting pencil...
A drafting pencil is basically a mechanical designed for precision drawing
because the guide pipe, usually 3-5 mm long, allows the pencil to move smoothly
along paper or the edge of a ruler. Also, the long pipe allows visibility as you
are drawing and the drawing to be well, precise. There are usually lead
indicators for people who draw because the lead grade is indicated and it is
useful for remembering. Also, if you have noticed, the drafting pencils come in
finer lead sizes such as 0.3,0.4 and larger sizes such as 0.9. Lead holders
usually come in large diameters such as 2.0 and 3.15.
A mechanical pencil is for daily everyday usage and the pipe is usually 2 mm
long. There are usually no lead indicators and the lead sizes are typically 0.5
I hope this helps you tell the difference.
For a review, I saw this pencil in China and I was hesitant to use it a lot
because it felt somewhat lightweight and cheesy XD. The pencil overall isn't the
best but for its price, it is a great deal.
