I agree with Architect. There are many good steels out there and there will always be an endless debate on steels and heat treatment and as to which is better, so it depends on the user as to which steel suits his or her needs. From plain carbon steel to rust resistant (stainless) steel, you have alot to choose from. Some knife "elitists" will look down on 440A, AUS-6, 420HC but there are many good quality knives with blades made from these steels and they're moderately priced.
As far as factory brands go, there are many qualiy knives produced by companies with great reputations. Stay away from cheap flea market knives and ripoffs.
Again, it's all up to you as far as which steel suits your needs. Do some research and also invest in a quality sharpening device to practice your honing skills and you won't be disappointed.
