With the polygons you’ve just resized selected, extrude both faces out as shown in this screen capture. There is actually an open hole left at the back end of the polygons, but this will actually not be a problem. We don’t have to worry about it, though you can cap it if you like.
Create a connection around the length of the handle. This will help constrain the mesh-smoothing.
Select the top two polygons and extrude them upwards to create some interesting feature on the handle. This is just an extra detail on the handle that gives it a little realism. Pull down handles are usually flat, but this is kind of a nice toaster; we might as well go the extra mile!
Select the side polygons on the object and adjust the width so that it’s almost touching the side of the mechanism slot. This will make sure there isn’t a significant gap there when we smooth later!
Create one more connection for good measure. We don’t want wanton smoothing, now do we!
