This was a Christmas gift from Stepson. I’ve used it a lot since it came to me, all-wrapped up in pretty Christmas wrap about 4 years ago. The base is made of natural marble and the slicing gizmo is nothing but taut wire. It comes with a spare wire all ready to be fitted to the handle.
You never realize how miserable a job cutting cheese can be until you’ve used one of these things. I doubt I can ever go back to slicing cheese with a knife ever again!
