There is no cursor in the cursor class called "Pencil", see the full list of cursors here:
Full list of cursors
However you can try custom cursors
Visual Studio allows you to create cursor files (.cur). The cursor file is a bitmap file with the extension .cur. To create a cursor file, right-click it and select Add New Item. After that, select the Cursor File item from the elements. This action will add a default Cursor1.cur file.

After adding the cursor file, you will be taken to the raster image editor, where you can change the bitmap using the drawing tools, as you can see

Now copy the Cursor1.cur file to the Debug or Release folder where your executable file is stored.
Once the file is saved, we can create a cursor from the cursor file using the following code snippet.
C # code:
this.Cursor = new Cursor(Application.StartupPath + "\\Cursor1.cur");
VB.NET Code:
Me.Cursor = New Cursor(Application.StartupPath + "\Cursor1.cur")
