Claim 0:
1. A hand trowel comprising:
a body member having an upper end and a lower end, the upper end including a hub member thereat, the lower end having a mounting member extending therefrom;
a shaft having a proximal end region and a distal end region, the proximal end region being secured to the hub member such that the shaft extends therefrom, the proximal end region having a plurality of external mating elements circumferentially positioned therearound and circumferentially extending perpendicularly therefrom to provide a radially varying contact surface having a plurality of keyways;
a blade member secured to the mounting member of the lower end;
a hand trowel handle secured to the upper end of the body member, the hand trowel handle including:
a handle having a front end region and a rear end region with a gripping member therebetween, the gripping member having an ergonomic shape and a discrete, selectively adjustable, rotational angle, the handle having a handle length which approximates a shaft length of the shaft,
the handle having a bore therethrough with a front opening and a rear opening, the bore having a plurality of internal mating elements circumferentially positioned therearound at the front end region, the plurality of internal mating elements selectively mating with the plurality of external mating elements to define a selectively adjustable, rotational angle of the handle, and
a locking member engageable with the shaft;

wherein upon the locking member being tightened into a locked, abutted relationship with the handle, the handle being in a locked, engaged position to reversibly lock the selectively adjustable, rotational angle; and
wherein upon the locking member being loosened from the locked, abutted relationship with the handle, the handle being in an unlocked, disengaged position to provide selective adjustment of the selectively adjustable, rotational angle.
