A hand-held scraper device containing a stowable multi blade pivoting head. The pivoting head is comprised of at least two scraping elements which remain at a fixed angle relative to each other while still allowing a pivoting action of the head assembly independently from the handle. The angle of the scraping elements relative to each other is set such that as the two scraping elements are jointly presented against the work surface they will be maintained at an angular attitude conducive to a scraping action in both a push and pull direction. The pivoting head can be collapsed for more efficient stowage or as an alternate configuration for specific scraping applications.

A push and pull shock absorbing scraper for selective scraping by a push and pull action includes an upper and lower scraper members for scraping ice, snow and frost from windows of a vehicle.

The O-ring is located between the head portion and the coil spring to further absorbs the impact force of the head portion of the scraper.

A wood scraper having two oppositely angled blades on a single head, and preferably two heads with two oppositely angled blades on each head. Thus, on both the forward and reverse stroke, there are two spaced apart blades scraping the work piece. This covers twice the surface area with the same effort as a single-bladed or single-headed scraper. All the blades are rigid and have a straight edge. All the blade edges are aligned with the planar surface of the work piece. This produces a level cut and makes the tool more stable, making gouging unlikely and enhancing the efficiency of the scraping action. The tool can be operated easily with one hand. In addition, the use of straight blades allows all the blades to be sharpened easily and quickly and at the same time using a belt sander or on a sheet of emery paper on a flat surface.
