No. A pair of $10 Harbor Freight concealable bolt cutters will take care of any cable lock I've ever seen.

Don't get me wrong, I use cable locks pretty much exclusively. They stop crimes of opportunity, which is 99.8% of what I am concerned with in my not insanely high bike theft area. 0.1% I take care of by parking my bikes next to much nicer bikes or where I can see it. The last 0.1% I just don't worry about, no method of securing is foolproof if someone wants your bike bad enough.

I have a U-Lock I use if I am leaving it for an extended period of time (i.e., overnight) in public.
