An angle controllable shovel is provided to reduce uncomfortable posture of a user and not to give unnecessary pain in back or in waist after an extended-hour work using the shovel. An angle controllable shovel includes a handle(20) and a blade(30) in which the blade can be bent at a certain angle by a physical force that is provided from a user. As the blade is manually inclinable, the user does not need to bend his/her waist to work. In this way, the distance between arms of the user and the blade is not far from each other, which in turn reduces a load upon the arms. With the angle controllable shovel, possible back pain or pain in waist from prolonged work can be prevented. |
