I'll look it up. Initially I am sure ANYTHING will be better than the current cutlery situation in my house. As of right now the best knife in the house is a Pampered Chef paring knife, but I just ordered a Rada cook's knife from a fundraiser catalog at work. I'm sure Rada is not as good as a Wusthof or Globe, but for $8 I figured it was worth a shot! In any case, the butcher shop at my local grocery store sharpens knives for free.
