For convenience, I've divided the belay devices in my collection into a number of categories. Although there are more rigorous methods to classify belay devices, I've chosen an informal approach that I think will be easier for most people to follow than some purely academic method.

Slotted "Sticht" Belay Plates
These are devices that are essentially flat plates with one or two slots that are used like a Sticht Plate.
Other Belay Plates
This includes plate belay devices that do not function like Sticht plates.
Slotted Blocks
This includes belay devices (other than belay tubes) that function in the same way as Sticht plates, but have irregular top and or bottom surfaces.
Belay Tubes
This includes ATCs and similar devices with no moving parts that have two rope channels defined by a single piece of metal. Each rope channel is rather tall compared to the thickness of the side walls defining the channel.
This includes devices that have one main rope channel that is split into two halves by a rod. The rod splitting the rope channel also forms an attachment for the keeper.
Lever Box Belay Devices
This includes the Grigri, Cinch, and similar devices that enclose the rope and have control levers.
Solo Climbing Self Belay Devices
Belay devices for roped solo climbing.
Everything else, including some nice devices.

A word on the tables…

The tables include some numerical data:

 ID  This is just my catalog number so that I can keep these straight
 Weight  Weights are in grams. Webbing, slings, etc. are not included unless they were supplied with the device. There is an exception: I put a 3 mm. keeper sling on many of my belay devices, and its weight is included.
 Height, Width, Thickness  I've given the dimensions in millimeters. The measurements are in perpendicular directions. I've chosen to measure the maximum dimensions instead of the most obvious dimensions. Sometimes this leads to numbers that are more than what you would expect - for example, the thickness of a bent plate would be more than the thickness of the unbent plate.
Standard Volume   The standard volume is just the product of the height, width, and thickness divided by 1000. This gives a volume in milliliters of a box that the device will fit into. Odd shaped devices are penalized by this formula, but since they are generally harder to pack, this number might be useful.
