Is aluminum a worthy material for a knife?

Aluminum is a soft metal that can deform easily and has low plasticity and melting temperatures. While its malleability and light weight make it ideal for uses where weight restrictions are critical, such as aircraft, for uses where it it would be exposed to continued rough use or heat, it is not ideal. It also cannot hold an edge like steel, steel alloys and many ceramics can.
An aluminum knife blade is possible. However, it wouldn't be the "go to" choice for most knife wielders or users.
