ABSTRACT:
A saw and water dispensing combination system includes a handsaw that includes a motor, a handle attached to the motor, and a blade mechanically coupled to the motor that is rotated when the motor is turned on. The blade is configured to cut through cement blocks. A shroud extends over an upper portion of the blade relative to the motor and a grip is attached to the motor distal to the blade. A container is provided that has water therein. A pump is fluidly coupled to the container and creates pressure within the container when the pump is actuated. An outlet conduit is fluidly coupled to the container. Water is forced into the outlet conduit when the pump is actuated and the outlet conduit ejects the water onto the saw blade. A coupler releasably couples the container to the handsaw.
