A good knife is a good knife whether or not it's for the home or pro kitchen. Wusthof Trident is the most seen in a pro kitchen and IMO the most durable with the easiest warranty service. In general, buy made in Germany, buy forged, buy classic styles. Brands to consider:

1) Wusthof Trident
2) Frederick Dick. (F Dick)
3) Messermeister
4) Henckel
