Dear Jose,

You stated:
"Does any of you know how much does it cost a Tungsten carbide knife
sharpener? I found a price here in Spain but I think it is excesive
expensive (nearly 15,000 US $) . Would like to know prizes in other places
(countries)"

Are you asking for a price for a machine that sharpens knives or are you 
asking for a company to sharpen your knives?
         There are two excellent U.S. companies that  sharpen 
tungsten-carbide blades:  Wasatch Histo (www.wasatchhisto.com) or Delaware 
Diamond Knives (www.ddk.com).
         Regards,
         Linda
