so that people could write
Pens with steel nips or if they didn't have that they would use a quill (which was "old" during this time) or they would use a pencil that took a lead and held it with a sliding ring that tightened the tips to hold the lead tight.
People in the Dark Ages had such things as the stylus, which was made of actual lead and were used for marking. The pencil, as we know it, has a core of graphite held in wood, and this was invented during the Renaissance.
The pencil was invented by Nick Forkeb in 1645 when he made a bet with former aviator Peter Belk. They bet to see who could create a material on which they could use to record famous information found during there journeys. Peter had no luck and therefore had to pay Nick 2,000 euros. Nick, who made the pencil, soon got it patented and had a successful career.
A o.7 mechanical pencil will do the job.
Yes ,as long as it has number two lead.
the .7 has nothing to do with the hardness of the lead. The number is the diameter of the piece of lead.
The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.
. it serves as the writing point of the pencil
lead is the most normal
The number of the pencil is based on the type of carbon lead used inside. The thicker the carbon lead gets the higher the number of the pencil becomes. If you notice a mechanical pencil is 0.9mm in diameter so it would be called a #0.9 pencil. A #2 pencil's lead is 2mm in diameter. So Why would we call a pencil a #3 pencil? Because it's lead is 3mm in diameter.
It's a pencil that looks rather like a pen, but has pencil lead in it instead of ink, and the lead moves down as you click and you can replace it with new lead.
It is called a lead pencil. Despite the name, the "lead" in pencils is actually made of graphite, not lead. Lead pens are typically mechanical pencils that use a lead refill.

A mechanical pencil is a Class 1 lever. The writing tip serves as the fulcrum, the effort is applying force on the pencil, and the load is the lead that is pushed out.
Mechanical pencils work by using a mechanism to extend a thin lead refill as you write or draw. The lead is held in place by a clutch mechanism that allows it to move in and out of the pencil tip. When you press down to write, the lead is extended, and when you release the pressure, the lead retracts back into the pencil.
