[Sca-cooks] Mezzalunas

[Pixel, Goddess and Queen]

This is a question for the knife people, mostly:

In the volumes of stuff that I acquired when my grandmother moved,
there is a shallow bowl and a mezzaluna. The problem with this particular
mezzaluna is that my table knives are sharper. How do I sharpen a curved
blade like this? Or am I better off finding a professional and letting
them do all the work?
