Indentation vise-wrenches

Abstract

The invention relates to indentation vise-wrenches; in use, interlocking pushed-out areas (“exdentations”)/pushed-in areas (“indentations”) of a fitting's inner surface/a pipe's outer surface are created by indenting units at indentation vise-wrenches' jaws. Neither pipes nor fittings of interlocked pipe-fitting combinations will move with respect to each other; even after total separation between the indentation vise-wrench and the interlocked combination. Embodiments include a tool comprising an indentation vise wrench; a tool kit comprising a set having at least two indentation vise-wrenches; a process comprising making indentation vise-wrenches; a process of interlocking pipe-fitting combinations; etc.
