Easy as pie. Last year I need to do a bunch of RF connections so I picked up a Klein crimper and a DataShark cutter on Amazon. Just checked my order history and both are still available.
Klein VDV211-048, $20.68
DataShark 70029, $13.52
The only 'gotcha' is to be careful with the cutter. The replacement blades in the handle are easy to snag a careless finger on. Sharp, those.
I used PPC brand RF ends and they worked flawlessly. I think PPC also makes BNC but a quick search on Amazon didn't show any. (Apologies to anyone who saw the Amazon link I first posted. That was for a different connector)
