The blade on this knife is nice quality bead blast 440C (plain) steel. This is a spring assisted knife, meaning when you push on the thumb stud to open it a spring takes over and propels the blade open (you can also activate the knife by pressing a flipper on the spine when the blade is closed). Spring assisted knives are legal in most areas. The body of the Xcaliber is made out of steel and features a rosewood insert on both the front and back of the knife pocket clip (tip up) ensures easy carry and access. The overall fit of the knife body is quite good as are the the action.
