Well, the web page for the connectors says you must use a particular compression tool. The one I use I bought from Cyberguys, but they don't have it anymore. The one they do have I would not buy. For cutting I use an inexpensive "coaxial cutter" from RadioShack and I also use their RG6 stripping tool.
I also have a DataShark compression tool but don't like it - it engages only one edge of the compression ring. It might be ok if the ring is metal, as DataShark's are, but not for plastic.
