I while ago I was looking into getting a cable laid under the private road between our house and garage. The option to dig a standard trench - say a 1 foot wide exists, and re-tarmac after.

I think it was a bit like a massive angle-grinder but I can't remember what it was called - can anyone help me out so I can know what to look for at tool-hire places?
It seems to me this would be ideal - quickly cut a tiny trench, drop an armoured cable, and make good, far more quickly than digging a proper trench.
