ABSTRACT:
A saw and impact resistant member formed of an elongated metal core having a longitudinal exterior surface and a thin wall metal sheath surrounding said core and in contact with said core surface at a finite number of contact lines with longitudinal spaces being formed between the interior wall of said sheath and the exterior surface of the core. The spaces are filled with a matrix formed of hard carbide particles and a soft binder material. The sheath is closely fitted on the core to exclude both binder and hard particles therebetween except in said longitudinal spaces.
