Definition
A handheld electric power saw with a narrow, straight blade that moves rapidly up and down (reciprocating motion) to cut curves, irregular shapes, and openings in sheet materials such as aluminum, plywood, plastic, and thin metal. Used in aircraft sheet metal work and general shop work for cutting holes and contoured shapes that a circular saw cannot make.
Plain English
A small power saw with a thin blade that moves up and down quickly. It is used to cut curved lines or holes in flat materials like sheet metal or plywood.
Context Anchor
Seen in aircraft maintenance, shop work, and repair discussions when a technician needs to cut a shaped opening or trim a panel.
Derivation
Named for the resemblance of its narrow, pointed blade to a saber — a long, slender sword. The shape of the blade gives the tool its name. Also commonly called a jigsaw.
Why Pilots Care
A saber saw can remove material quickly, so it must be used carefully around aircraft parts, wiring, hoses, and structure.
Intuition Check
Do not read “saber” as a flight term here. A saber saw is simply a cutting tool with a small moving blade.
Example Sentence 1
The mechanic used a saber saw to cut an inspection opening in the aluminum skin.
Example Sentence 2
With the saber saw he cut a precise opening for the inspection plate without damaging surrounding structure.
