Definition
A hand-held cutting tool consisting of a rigid frame that holds a thin, fine-toothed replaceable blade under tension, used to cut metal, plastic, and other hard materials.
Plain English
A small saw with a thin metal blade stretched tight in a frame, used for cutting through metal and similar hard materials by hand.
Context Anchor
Seen in aircraft maintenance, sheet-metal work, tubing work, and general hangar tool discussions.
Derivation
From 'hack,' meaning to cut roughly, plus 'saw.' The name reflects its origin as a tool for rough metal-cutting work.
Why Pilots Care
Correct use of a hacksaw prevents damage to surrounding aircraft structure and produces clean cuts that maintain the integrity of safety-critical parts.
Intuition Check
Do not read “hack” as careless work here. A hacksaw is a specific cutting tool, and in aircraft work it must be used carefully and cleanly.
Example Sentence 1
The mechanic used a hacksaw to trim the excess length off the new control cable bolt.
Example Sentence 2
During the repair, a hacksaw was used to carefully section the damaged exhaust pipe without scoring the adjacent skin.
