I am not advocating your cutting up of other peoples property, but if I were thinking along your lines, I would take along a pair of fencing pilers (I just grabbed this link from google, you can find them in just about any hardware store). With them you can cut bob waar, cyclone fences, etc, pull staples, drive staples/nails/tent pegs, etc, and they don't weigh a ton. Bolt cutters, even little ones, weigh a lot...
