Sometimes you may want smoothness on one area of a mesh object but not on another. For example, on the rubber grip we want the top to be rounded and smooth. But on the bottom, where it fits over the plastic air hockey paddle, we want a sharp edge.
You can produce this effect by adding creases to selected subobjects within the mesh. Subobjects can be faces, edges, or vertices. To make it easier to view the bottom of the rubber grip, I turned off the layer with the paddle geometry. Viewing the rubber grip from below, you can then hold down the CTRL key and click on the bottom face to select it.
The default option, Always, means that it will be creased at all levels of smoothness even if you increase the smoothness after applying the crease. I used the default Always option for the rubber grip.
