i have read many threads on how different razors like to finish off on different stones, i own a 1/4 hollow wacker, some wedge sheffields, dd goldedge,henckle,boker,griffon,torrey,and i have a set of naniwa hones,1000- 5000-8000-12000. my question is do i need a coti or some other finish stone for this list of razors,or the naniwas should handle the job?
