Butchering a large animal– Tool Bleg

So, I was able to get ahold of a large case of pork necks.  Skin’s already gone, but otherwise most of the pieces look to be the complete neck.  Since they’re for the dogs, I need to break them down into smaller pieces, especially for Arty.  I’m thinking a hacksaw, but is there anything else that might work better?  Money is, as usual, an issue, but since I expect to be able to source pork necks and other similer pieces from this supplier on a regular basis getting something that’ll DO the job is worth it.  Any suggestions from you hunter/farmer people?
