Similarly, I've added in two edges along the height of the toaster for good measure. In the long run, this will help us constrain the smoothing around the toaster pull-down mechanism that we'll work on next.
The toaster object is symmetrical, and we've used our symmetry modifier to make that clear, so select the edges shown in the image and inset them. The selection shown is a little strange, I understand, but because it's symmetrical we needn't worry because the end result will look fine. This action completely limits any smoothing around the mechanism to stay in this area.
Insetting the faces also affords us the luxury of simply deleting the faces. This will lead us into a new method of modeling where you copy faces and weld vertices together.
Let's double-check our toaster model, shall we? It's looking pretty nice considering all the pain we've put it through. We're going to attempt a rather tricky procedure; over the next few steps we're going to collapse, and re-instate our symmetry modifier.
Right click the symmetry modifier in the stack and remember its settings. Right click on the modifier and select "Collapse To". Then, place another symmetry modifier in its place with the identical settings. Make sure the modifier is between TurboSmooth and Editable Poly, or it won't look quite right. Also, make doubly certain you don't click "Collapse All" or you'll include the T-Smooth in there too! Yipes!
