Hi Bill, I will put my two cents in about knives. The very best knives for maintaining and getting a sharp edge are carbon knives, alas, they are easy to rust and high maintainence. High carbon stainless steel, takes care of the rusting and the edge is not as good but acceptable. All the knives mentioned in this thread are high carbon stainless steel. Having it forged from one piece adds durablity, the steel should be the length of the knife with solid rivets to hold it in place. Some rivets you cant see because the handle appears solid. As far as which knife...once you have a well made knife as all of these knives are...what makes it the knife for you is how it balances in your hand, how the grip feels with your hand wrapped around it and your preference on style if any. Some grips are made for men, and women's hands are too small to feel comfortable, some knives are heavier than others and it is totally subjective as to whether this is a good or a bad thing for you.
Try going to a store that carries several brands, try them all out...trust me when you hold the knife that fits you, you'll know. After finding out which knife is right for you, go online and get your best price.
A knife that fits you properly will cut your work in half because you'll make your cuts quickly and effortlessly. A chef's knive (again size is determined by you), a boning knife and a paring knife are usually all anyone needs.
I hope this helps...
