Is this a good one?

I've been looking at a hone that will touch up my razor, I've done some reading about barber hones and I know that most of the good ones such as Swatty's keen kutter and such but I cant seem to find any opinions on this one VINTAGE DURO RAZOR HONE- STONE MARKED CROWN-BOXED - eBay (item 250790589253 end time Mar-25-11 18:43:36 PDT)

I was just wondering if it is what I'm looking for?

There was a HUGE review of barber hones a while back, do a search it might be in there.
