My Wife's mother is departing to Bangkok later today, as a cheese lover I hold back on purchasing the larger cheese's I could buy purely because I can't cut them properly, Does anyone know of a shop that sells the above item that she could buy for me, I live in the N/East of Thailand and have never seen this item.

You can order one on line from Aliexpress :http://www.aliexpress.com/w/wholesale-cheese-slicer.html I buy things fro them all of the time and have never had a problem.

I don't know if you have a Rimping Supermarket in your area, but they had them in stock in July. They were a little on the expensive side, from memory.
