Abstract
Several embodiments of trowels which have an elongated handle and a pair of generally facing weights or a weight or weights and a connector between which a pair of blades are secured with one blade being of lesser height than the other to thereby resist undesired flexing of the other blade. In another embodiment, in lieu of having a second blade, a second weight which is disposed on the opposite side of the blade from the handle, has a downward extension which limits flexing of the blade. In a further embodiment, a blade is a two component blade and has a detachable and replaceable cutting edge. The weights and connector serve a multiple purpose of securing the upper end of the blades therebetween, facilitating downward pressure when the trowel is in use and in some embodiments through either a second blade or an extension of a weight for limiting the amount of flexing of the blade.
