It's a compression "crimper." Much much better than the traditional hex crimper nonsense. I got mine from eBay, Zenith brand with 20 Thomas & Betts compression connectors for $25 shipped. Well worth the price, compression connectors are so much faster and cleaner. The cable stripper I got from another auction, don't remember the price, but I think it was around $5-6 shipped.
Here's the guy I got mine from:
