Illustrator provides the following tools for reshaping objects:

The Rotate tool (R) rotates objects around a fixed point.	The Reflect tool (O) flips objects over a fixed axis.	The Scale tool (S) resizes objects around a fixed point.	The Shear tool skews objects around a fixed point.
The Reshape tool adjusts selected anchor points while keeping the overall detail of the path intact.	The Free Transform tool (E) scales, rotates, or skews a selection.	The Blend tool (W) creates a series of objects blended between the color and shape of multiple objects.
The Warp tool (Shift+R) molds objects with the movement of the cursor (like molding clay, for example).	The Twirl tool creates swirling distortions within an object.	The Pucker tool deflates an object by moving control points towards the cursor.	The Bloat tool inflates an object by moving control points away from the cursor.
The Scallop tool adds random curved details to the outline of an object.	The Crystallize tool adds random spiked details to the outline of an object.	The Wrinkle tool adds wrinkle-like details to the outline of an object.
