for trueing metal, wood, and plastic surfaces which have previously been
machined or filed.
Other scrapers are made to remove paint, stencil
markings, and other coatings from various surfaces.

Scrapers are made in several different shapes
and for varied work.

spring steel blades with flexibility controlled by a sliding ferrule.
