What is that? Bi-metallic? And why is it bi-metallic? So it can curl-up if it hits something live?
Irwin sez:
--
With a bi-metal blade, the edge of the blade is constructed of a high
speed steel while the body of the blade is made of spring steel. The
two sections are welded together to form a single blade. The
advantages of a bi-metal blade is that the hardened edge of the blade
stays sharp longer than a standard carbon blade and the spring steel
body allows the blade to flex without breaking which is common among
carbon body blades.

So we have homo-metal, bi-metal, is trans-metal next?
