hone down into

[Herb Stahlke]

I've heard or read "hone in (on)" often enough not to be struck by it
anymore, but today I read "hone down into" in the sense of "drill down
into" or "explore more deeply."  The writer is usually pretty careful, so
it surprised me  I suppose it could come from "hone in on."  I don't see
any link to "home in on."  Google gives 60K raw hits.
