ABSTRACT:
A blade wrench includes an adjustable interconnection disposed between the tool body and the blade portion which permits selective angular positioning of the blade portion of the wrench relative to the tool body. The blade portion may thus be adjusted and fixed at a selected angle to facilitate alignment with and purchase on a fastener. The adjustable interconnection comprises apparatus for selectively angularly positioning the blade portion relative to the tool body and a locking device for maintaining this angular relationship.
