Hi there, My name is Blaine i am just starting up a sharpening bussiness. I not sure what sharpener i should buy i like that looks of the Tormek it seems pretty easy? i more need it for doing commercial,and house hold knives . but i was woundering if the tormek could do and serated knives??? , as well i would like to know with the tormek if i had to do 150 knives a day what would the best way of sharpening so many be ? with only one stone i am not sure if i could go through the whole 220 grit then shave it down to the 1000 grit ,wouldn't you be starting the next knive at the 1000 grit first then?? maybe you have a better idea or a differnt sharpener in mind? thanks Blaine
