发明名称 Trowel with levels
摘要 A trowel includes a series of levels embedded in the handle for measuring the inclination of a surface being finished. The trowel includes a flat base plate, with a handle having two ends each secured to the plate to define a grip area therebetween. This construction provides an extremely rigid structure, where the handle and its included levels cannot flex angularly relative to the base plate or blade. At least one of the handle ends, and optionally both ends, includes two mutually orthogonally disposed level indicators installed therein for simultaneously measuring the level or slope of a surface being worked, in two mutually perpendicular axes. The opposite handle end may also include a pair of similarly arranged levels, if so desired. The levels may comprise bubble or spirit levels, electronic levels with audible output, and/or other level types as desired.
