Definition
A hammer whose striking face is made of a softer material than the workpiece it strikes — typically rubber, plastic, rawhide, brass, or lead — used to deliver blows without marring, denting, or damaging the surface being struck.
Plain English
A hammer with a soft head, used when you need to hit something hard enough to move it but gently enough not to leave a mark or cause damage.
Context Anchor
Seen in aircraft maintenance and shop work when a part must be moved, seated, or loosened without marking it.
Derivation
“Face” means the part of the hammer that actually strikes the object. “Soft-faced” points to that softer striking surface, not to the whole hammer being soft.
Why Pilots Care
Prevents damage to delicate aircraft surfaces, skins, and instruments that could create safety issues or require expensive repairs.
Analogy
Like using a rubber mallet on a car body panel instead of a metal hammer.
Intuition Check
Soft-faced does not mean weak or harmless. It still delivers a solid hit; the softer striking surface helps protect the part being struck.
Example Sentence 1
The mechanic used a soft-faced hammer to seat the wheel bearing without scoring the race.
Example Sentence 2
A soft-faced hammer allowed the technician to seat the inspection cover without scratching the paint.
