Cons: dull, work poorly.
I was given this as a gift. Sadly, the tools are poor for their purpose.
The paring knife is dull, the handle is sort of triangular in cross section and uncomfortable. The sheath is a good idea for a ceramic blade, but in the end it just didn't matter.
I had high hopes for the peeler. It is a right hand use only unlike most common peelers that are leftie friendly. And it too is dull. Struggles on cucumbers and largely failed on carrots. The idea of a ceramic peeler seems like a great combination, but this is a poor execution of the idea.
Maybe my set is a poor example but I'm not interested in finding out anymore.
