Abstract: In accordance with the present invention, a multi-use broad bladed knife is provided. The multi-use knife includes a broad blade, such as commonly used to apply spackle to a wall or other surface. The broad blade is attached to a handle, with a striking surface comprised of an appropriate hard material on the heel of the handle. Within the handle are slidably extendable and retractable implements, including a cutting edge and a screwdriver implement.

The screwdriver implement and cutting edge may lock into place when extended for use and may also lock in place when retracted within the handle.

Abstract: A lifting tool has a handle, a lifting tool head, and a means for slidably mounting the lifting tool head on the handle such that the lifting tool head slides with respect to the handle between an extended position and a compressed position. The lifting tool further includes a means for biasing the lifting tool head towards the extended position. Since the lifting tool head can slide against the bias of the means for biasing, the lifting tool can absorb some of the shock if the lifting tool head strikes a hard obstruction, thereby sparing a user from the strain and potentially avoiding an injury that could result from the strain.

Abstract: The present invention is directed to a scraper suitable for use in removing material adhering to flat surfaces, e.g. paint. In the presently preferred embodiment, the scraper comprises a blade body, a scraping surface and a handle. The scraping surface extends longitudinally along a bottom edge of the blade body while the handle is affixed to a top edge of the blade body. The blade body comprises an elongate, flat body constructed of a rigid, yet flexible material, e.g. steel. The blade is characterized by a pair of angular bends dividing the blade into a center portion and two end portions, each portion being in a different plane. The bends are preferably positioned on opposite sides of the handle, more preferably equidistant from each end of the blade body. The end portions are angled to opposite sides of the center portion so that the angles are complementary, resulting in the end portions being generally parallel.

Abstract: This invention consists of a bias adjustable impact scraping tool that has a bias spring selectively positionable in a first region or a second region respectively for biasing or un-biasing a cutting blade for scraping material from surfaces when the surface is above or below the cutting blade. A ramming member for transmitting externally applied thrust forces to a scraping member is telescopically and slidably mounted to the scraping member which may be biased or un-biased relative to the ramming member by selectively positioning the bias spring. A removably mounted partition sleeve located within the ramming member partitions the ramming member into first and second regions. When the bias spring is held within the first region, the scraping member is biased by the bias spring to remain distally extended during a thrust cycle of the tool thereby urging the cutting blade to remain in contact with the surface.
