Willie,
You are looking at the relief. This type of reamer is commonly used in watch and clock making. All they are is a pin (tapered in this case) with half of it cut away to the centerline, to create sort of a half moon shape. As long as the cut away part is exactly on center, they will cut and make a very round, very precise hole. A lot of guys use this technique to make chamber reamers, because they are so easy to make.
