摘要： A dusting tool having a flexible skeletal element including a base, from which four elongated arms extend. The elongated arms have a base end and a distal end. The base ends extend from the base and being spaced apart from one another at the base. The arms being flexible and resilient. A plurality of cross-members extend between the elongated arms, a plurality of living hinges being disposed between the plurality of cross-members and the elongated arms. A force applied to at least one of the elongated arms is transmitted to the other of the elongated arm by the plurality of cross-members and the plurality of living hinges.
