It is also known in the art that surfaces to be treated with conventional scrapers may range in various shapes and sizes, such as walls, floors, ceilings, wooden surfaces, and others, as well as rooms, platforms, furniture, boards, frames, and the like, for example.
These manual scrapers generally comprise a handle and an end operatively connected to an extremity of the handle for scraping the upper surface of a layer to be removed.
It is also known in the art that very often, for various time or financial constraints, ft is very important to remove said layers and residual portions of materials as fast as possible, while preventing any harm such as scratches, cutting, and the like, to the users of these manual scrapers. However, conventional scrapers are not always optimally designed for allowing an ergonomic use of the tool, for extended period of portions, and/or for an improved scraping of the material.
It is also known in the art that some conventional scrapers may be conveniently used for scraping surfaces and the like, but unfortunately, are not always designed so as to prevent the occurrence of undesirable damages to the surfaces being treated, therefore occasionally causing unwanted notches and other damages on the surfaces to be scraped, which subsequently need to be repaired, etc., which is disadvantageous, for obvious reasons.
It is also known in the art that most conventional scrapers are very task specific, and thus are not ultimately designed so as to enable to carry out a variety of tasks. For example, most conventional wallpaper scrapers are not provided with suitable means so as to enable to subsequently install new wallpaper on the surface having been treated (stripped), so as to not only appose the wallpaper onto a given surface, but also enable a proper seam formation between two adjacent sheets of wallpaper, for example.
