Hello Josip,
Barber hones were & still are used to refresh a razor's edge, but a barber hone in the hands of a person who has not honed before , can dull an edge even more.

You don't necessarily need a set of hones, you can purchase a finisher.

Use the "Advance" search feature , above right, put in key words whatever you want to learn about,,,, such as finishing hones, barber hones, refreshing a razor,,,etc.
