Working with Cut-n-Nut:
Cutting Threaded Rod:
Most bolt cutters mash one side of the threads, so I use a file:
Using the corner of the file, make a really deep groove around the rod.
Bend to break
File down any burrs or sharp edges.
Cut between the holes, straignten any warping with pliers. You may also want to file off sharp edges.
Bend cut-n-nut along the holes, for small peices this can be done by
holding the piece in pliers and folding over against a desk.
