The pen tool is the hardest tool that you will come across in Illustrator if you are just starting out on illustrator but if you master it, you open the door to a whole new world.
So let's begin our conquest of the world of the Mighty Pen Tool.
Even for beginners it isn't difficult to spot the pen tool in the tools palette. If you are unsuccessful in your attempt to locate the pen tool just hit P in your keyboard, your cursor automatically turns to the shape of a Pen Nib. Now just look at the tools palette to see which tool is selected. There you'll see our mighty pen tool.

Not very difficult isn't it?
Now let's further explore the pen tool. If you click on the Pen Tool button a sub menu pops up giving us various options. The following picture shows us the sub menu.

Let's find out of what each of these tools does.
The first one from the left is the default Pen Tool. It is used to draw paths just like you use a normal pen to draw on paper. It's shortcut key is P
The second from left is the Add Anchor Point Tool which adds an anchor point to an existing path. An anchor point, as the name suggests are special points along a path which can be manipulated to change the direction of the path. It's shortcut key is + (plus). Try to invoke the tool by clicking the + key in your keyboard. Pressing the + key in the Num Pad may sometimes bring up other tools.
The third one is the Delete Anchor Point Tool. You might have already guessed what it does. Well if you haven't, don't worry it just deletes existing anchor points along a path. It's shortcut key is - (minus)
The last one is the Convert Anchor Point Tool. By now you already know what an anchor point is and what it is for. This tool helps us to manipulate an anchor point like changing the direction of the path.
Now we should try out each of these tools to put into practice what we have learned.
Create a new document in Illustrator. By default you will have the Selection Tool (shortcut key V) selected. Select black as your stroke color and none as your fill color. Use the following figure for reference.

Hit P in your keyboard and the Selection Tool will turn into Pen Tool. Tada!
Now click anywhere on the document with the Pen Tool and pull up. Hold down the Shift Key to make sure you keep to a straight line. Release the mouse bottom. You have just created your point A. The whole point of holding down the Shift key is to pull in directions of 0, 45, 90, 135, 180, 225, 270, 315 and 360 degrees around the anchor point.

Now click on another point a little away from point A. Hold down the Shift key and pull to the right and release the mouse button. This is the point B. You might also notice that the points A and B are now connected by a curved line. Well this is your first path in Illustrator, CONGRATULATIONS!

What difference did it have from drawing a curved line on paper? First off all, the curve you got was the smoothest you ever drew in your life. Secondly it was much quicker than drawing on paper, just 2 clicks of the mouse and you are done. But what did you miss? Of course that soothing feeling of drawing on a paper with a pen.
Well, that was easy but hold-on there are a few other tricks as well that you need to learn to master the Pen Tool.
The curve you created looks alright but wouldn't it be much cooler if it was a reverse curve instead of a simple curve. A reverse curve is one which changes it's direction twice, at least that is what they taught me in my Transportation Engineering class.
OK here is where the Add Anchor Point Tool kicks in.
Hit + key in your key board to select the Add Anchor Point Tool and click on the curve as shown in the figure below to create a Point C. You notice that on either side of the point C, two handles also crop up on either side of point C.

These handles are going to help you create a reverse curve.
Hold Shift+C to bring up the Convert Anchor Point Tool. Click on point C then press Shift (this is very important, if you press shift key first and then pull the whole curve moves) and pull in the direction shown in the following figure.

Well the curve isn't exactly a reverse curve, the angles need to be much greater than this, like this.

….well may be this is too much of a reverse curve LOL. Never mind this one augers well for demonstration purposes.
Although the symmetry of he curve is lost as it was a quick work, take a note of the points where I have made Anchor Points. You'll notice that I have made Anchor Points at the summit of the curve as well at the valley. This is the best practice as it gives you greater flexibility, if you have to make any changes to your curve in the future.
Now we have covered three tools namely Pen Tool, Add Anchor Point Tool and Convert Anchor Point Tool and that leaves us with the delete anchor point tool. As you continue your journey towards mastering the pen tool you'll come across one or two points in your path that you feel do not fall in line. Well, then it's time to KILL THEM! Meet your asset (CIA code) Mr. Delete Anchor Point Tool. He is a nasty tool and kills without mercy. There will not be even a trace of the poor victim. Let's master him.
Let us try it on our poor unsuspecting Point C. Hit V. Select the path ABC we created. Hit the - (minus) key in your key board to activate your asset (Delete Anchor Point Tool). Sneak behind the point C, once you have positioned right on top of Point C, click (Bang!)


Now hit Shift+C to select the Convert Anchor Point Tool and use the handles projecting from Point A and/or Point B to change the degree of the curve.

You could make all sorts of crazy shapes using the pen tool. Try making the following shapes.

As a logo designer this tool is my best companion. I draw logos in a Quad Ruled Book, Trace it on a tracing paper with a fine tipped pen, scan it using my HP Scanner, place it on Illustrator and trace it with the Pen Tool. I would soon write a post on my logo design process.
I hope you have enjoyed this short tutorial. As they say practice makes perfect and soon you'll drawing complex shapes like this.
