Toasters, as has been stated before, are fairly straightforward, even mundane items, and generally serve exactly one function, making toast. But there are some specialty toasters out there that either take on one specific job and do it well, or pull double duty in various ways.
The bagel toaster
will, of course, make toast, but it is designed with the bagel in
mind. The slots on bagel toasters are at least 1.5" wide to accommodate
the halved bagels. The 4-Slice Bagel 24645 Hamilton Beach Toaster
and the B1035 Bagel Perfect Toastmaster Toaster, for a couple of
examples, have both wide slots and special settings to toast the
cut side of the bagel and keep the other side warm and chewy.
The patented Radio Toaster combines a fully customizable radio with, you guessed it, a toaster. This space saving little wonder does both jobs admirably.
For multifunction madness it's hard to beat Back to Basic's TEM500 Muffin & Egg Toaster Cooker/Poacher. While muffins, bread or bagels are toasted a side unit simultaneously steam poaches and egg and heats a pre-cooked meat patty for a delicious breakfast sandwich in 4 minutes flat.
Perhaps the most unique toaster we've run across is Duchcambell's Hot Diggity Dogger Hot Dog Toaster. This hilarious and handy little contraption has two cylindrical wells for heating hot dogs and two extra long/wide slots to vertically toast the buns.
