Thread: Stell is the only blade material?

It dawned on me today that the only material I have seen being used for blades is of the steel variety. At first I asked myself, why not aluminum? It's much lighter and does not experience rusting (at least not due to oxidation). Then I realized how easy it was to work with and bend and such, and I concluded that it must be just too soft of a metal. But what about titanium? Maybe titanium is too difficult to hone after it has left it's manufacturer. Anyways, I am curious if any str8 companies/individuals/hobbyists have ventured into experiments with different metal types and why steel remainds utterly dominant.

EDIT: *Steel, not stell
