I'm not sure if this is the most functional scale, but it sure is pretty. The weights are made from solid metal and come in nine pieces from 5g - 500g.
This kitchen scale combines a dishwasher safe mixing bowl with style and design. We love the clear glass bowl that inverts for neat, dust-free storage. Max Weight: 5-lbs/2.2-kg and sensitivity: 1-oz./25-gr. There's even a rotating dial for quick reset to zero.

This is only a concept, but it is pretty cool. It is a cutting board that also acts as a scale, so you can cut and measure on the same surface.
