A tool having two adjacent blades, for working fluent materials such as cement, plaster, and epoxies in corners and other angled areas, is shown and described. Each blade is angularly adjustable with respect to an included angle defined between the two blades. The tool may have right and left blade portions pivotal along abutting or adjacent edges, and a linkage including a releasable clamp to establish and secure desired working angles between the right and left blade portions. The tool has two pivot axles, one for supporting each of the right and left blade portions.

A tool is shaped for working a mud patch in a shower enclosure. The tool has front and rear edges with sections angled relative to each other to allow easily contacting angled edges of the walls of the shower enclosure.

A spackling tool for spreading and smoothing spackling includes a main planar flat blade made of a thin resilient material. The blade is substantially rectangular in shape with left and right side edges and front and rear edges. In one embodiment, a left blade is formed by bending the material forming the main blade upwardly at an angle of substantially 90 and a right blade is formed in substantially the same way at the right side edge of the main blade. A handle is secured to the rear edge of the main blade at the midpoint thereof and extends away from the main blade in substantially the same plane as the main blade. In a second embodiment, the left and right blades are hinged to the main blade so that the angle between them and the main blade can be adjusted.

A knife that includes a blade, a handle affixed to an end of the blade and a screwdriver bit fixed to the handle and moveable between an extended position beyond the base of the handle and a retracted position in which the screwdriver bit is arranged completely within the opening of the handle.

Electronic trowels, systems and methods of applying a layer of material using the present electronic trowels. The various electronic trowels include a handle, at least one blade, and one or more sensors residing on or within the trowel. The trowel is for applying a layer of material over a surface area, whereby the one or more sensors detect and collect material installation data during application of the layer of material over the surface area. One or more electronic devices coupled to the one or more sensors receive and analyze the collected installation data for monitoring and controlling the application of the layer of material to ensure a desired end product is achieved. Application errors may be detected before, during, or after the installation process.

A spreading tool allows width and depth variation of the spreading blade. A plate has first openings and second openings along with a first bottom edge. A blade has slots and is pressed against the plate so that the slots each align with a respective one first opening and a securement bolt is passed therethrough, the blade slid up or down against the plate so that the lower edge of the blade extends a desired distance below the bottom of the plate prior to bolt tightening. An extender has third openings and is pressed against the opposing surface of the plate so that its openings align with the second openings of the plate with securement bolts pass therethrough. A lower edge of the extender aligns with the bottom edge of the plate and extends beyond a side of the plate.

The present invention provides a modified finishing trowel tool comprising a blade having a contact surface with a planar and convex component. One edge of the longitudinal edge of the blade is configured with a protruding convex surface such that when pushed or parallel with the trowel handle a uniform concave channel way is formed along the surface of the semi-cured cementitious surface. Thus when the trowel is oriented in a substantially horizontal position along the surface and moved along its longitudinal direction, a concave indentation is created in the cementitious material. This trowel is particularly useful in forming a uniform drainage ditch along the surface of the final, cured cementitious material such as along the perimeter of a cement basement floor.

A hand tool is provided for the application of joint compound on wall board, a planar blade affixed to a handle. The blade has a concave arcuate working edge, wherein the concave arcuate curve extends the entire length of the working edge to each corner of the working edge. The concave arcuate working edge to may be used to apply a self-featured layer joint compound over drywall tape on planar butt joint or an inside corner joint. The blade is laterally flexible.
