Quoted from jibmums:I've found that a wire jig really isn't necessary, and in fact will actually give you exaggerately rounded corner bends unlike the original piece. Just hold your wire in a vise or a pair of pliers and bend by hand over the corner. Put a couple of pieces of painter's tape on the tool first so the sharp edges don't bite into the wire. The result looks much closer to the original.
Same here, a vice and pliers give perfect results !
