A combined net structure is disclosed that comprises a non-planar coarse net with a grid-like structure comprising a plurality of coarse cables wherein longitudinal coarse cables intersect with latitudinal coarse cables to form a plurality of coarse cells and cutouts of a fine net attached to the coarse net, wherein the fine net comprises a plurality of adjacent fine cables. Each non-edge fine cable is attached to two adjacent fine cables on each of its sides at a plurality of locations along their lengths forming attachment points, wherein the fine net is arranged in a form of an array of fine quadrangular cells with said attachment points constituting the vertices of the fine quadrangular cells. System that comprises the combined net structures are disclosed as well.

An article of manufacture for providing an easy wire-crimping tool according to the present invention includes a wire-crimping tool according to the present invention for accepting a crimping sleeve having two or more wire members within the crimping sleeve to crimp the crimping sleeve and the two or more wire members together. The wire-crimping tool has a crimping tool body having one or more lower crimping teeth, a crimping tool head having one or more upper crimping teeth configured to interlock between the lower crimping teeth to create one or more pinch point crimps into the crimping sleeve, and a crimping power source coupled to the crimping tool body and to the crimping tool head to cause the upper and lower crimping teeth to move together when a crimping sleeve is in between.

An apparatus for twist tying wire around intersecting rebar bars. The apparatus is configured to receive and discharge precut wire segments, form and wrap the wire around the rebar, and twist the wire securely around the rebar. The user merely positions the tool at the rebar intersection, release a wire segment into the work end of the tool, and with a single fluid motion move a slide mechanism up to bend the wire segment around the rebar and twist it about itself to tie the rebar together.
