Sur La Table has this cheese knife set designed by Coltelleria Saladini in collaboration with Alberto Marcomini an expert ager of cheeses in Italy. The knife is forged using AISI 420 stainless steel and the handles are made from Tuscan olive wood. The price of this set is $2,000. Ouch.
If you like this set, though, you can purchase separate knives by the same designer at Formaggio Kitchen. Individually, the knives will cost $100+.
