An improved trowel for facilitating the production of air pockets in a layer of mortar mix applied to a substrate for receiving marble-flooring pieces thereon. The trowel comprises a handle and an elongated blade joined together by a shank. The shape of the blade gradually narrows to a distal end that includes a plurality of tips separated by one or more V-shaped notch or notches. In various versions of the invention, the number of tips may vary and the tips may be flat or pointed. The V-shaped notch or notches may vary in depth.

What is claimed is: 1. A trowel for spreading a quantity of a mortar mixture, comprising: a handle and an elongated blade joined together by a shank; said blade constructed from a single uniformly thick sheet of metal having upper and lower surfaces terminating at a contiguous perimeter edge joining the upper and lower surfaces, such that a volume of mortar mixture disposed upon the upper surface can slide off of the upper surface and around the perimeter edge in a completely unimpeded fashion; said blade further defined by a broad area adjacent to the handle that is void of any passages having a size enabling the mortar mixture to pass directly through the blade; said blade having a geometry gradually narrowing from said broad area toward a distal end thereof; a crease formed within said blade, said crease located parallel to and substantially along a longitudinal axis of the handle, and terminating about a continuous perimeter edge; said blade having a gradually narrowing shape defined by edges extending to a distal end; said distal end having a plurality of tips; said tips being spaced apart and separated by at least one V-shaped notch provided in said distal end; whereby said trowel may be manually manipulated to control the movement of said mortar mix material about said tips and along said edges and said at least one V-shaped notch to produce air pockets in said mortar mix. 2. A trowel as recited in claim 1, wherein: said plurality of tips number from two tips to approximately four tips; and each of said tips narrows to a point. 3. A trowel as recited in claim 2 wherein, said at least one V-shaped notch has a depth in at least one range selected from a group of ranges consisting of: (a) a range of 1.5 to 7.0 inches (3.8 to 17.75 cm), and (b) a range of 2% to 90% of the length of said blade. 4. A trowel as recited in claim 1, wherein: said plurality of tips number from two tips to approximately four tips; and each of said tips narrows to a flat. 5. A trowel as recited in claim 4 wherein, said at least one V-shaped notch has a depth in at least one range selected from a group of ranges consisting of: (a) a range of 1.5 to 5.0 inches (3.8 to 12.7 cm), and (b) a range of 2% to 90% of the length of said blade. 6. A trowel as recited in claim 4, wherein said at least one V-shaped notch has a depth of approximately 1.5 inches (3.8 cm). 7. A trowel as recited in claim 4, wherein said at least one V-shaped notch has a depth of approximately five inches (12.7 cm).
