It is not a wire cutter like the MP600 Cable Cutter or the SOG Powercut this cutter was apparently designed for the military to cut concertina wire (coiled razor wire opposing armies like to litter the battle field with), it has a cutter on either side of the head so you can attack the stuff either on an up cut or a down cut without having to turn over and maybe getting yourself shot.
Could be of use to farmers, but I believe a normal fencing tool would be more practical and cheaper.
