Beauty- look of the design is appealing and even if it for functional use such as the juicer it is still considered art. The design is "neat and fun".

Functional- He describes the knife under the juicer and he talks about how its really sharp and the curve in the knife is to help with the handling of the knife.

Reflective- He says the design can tell you stories and talk about the emotion and the feelings you get from the design (visceral and behavioral).
