The powere sabre saw is typically a larger more powerful jigsaw and is usually referred to generically as a reciprocating saw. The main distinction between the sabre/reciprocating saw and the jigsaw is that its overall appearance is somewhat reminiscent of a sabre sword. Its use in the hands is more typically against vertically standing objects unlike the jigsaw which has its primary use for cutting horizontally across surfaces. The sabre saw consists of a reciprocating cutting implement, usually a toothed blade, to chiefly cut through wood and other various materials. Due to its large blades (relative to the jigsaw) its primary use is to slice material handily, rather than using the traditional circular saw in the application of building homes. It's also an advantageous implement when cutting into tight crevices.
