What are the factors that lead you to buy a particular knife? Rank these features: price, maker, where it's made, type of blade (carbon, stainless, ceramic), handle type, etc.?
It depends on the use of the knife.
-- If I am going to be using the knife in a public kitchen on a daily basis, then I look for the most comfortable knife possible for my hand that can maintain a decent edge. Normally, for this application, I don't look for an expensive blade because things have a tendency to "walk-off" in a public kitchen.
-- For my travel "kit", I use mostly production blades that I am comfortable leaving behind if necessary. Again here, if you travel allot and go from kitchen-to-kitchen, you don't want to have a very expensive and treasured blade end up in someone else’s hands.
-- For personal use at home, I look for blades that have a balance of form and function. I want quality in the steel and I want it to look presentable as well. I want the blade to hold an edge for a long time, because I am the one doing all of the sharpening.
-- For specialty tasks, I always get specialty blades. I can't live without my uber-sharp flexible filet knife. For breaking down larger primal cuts of meat, I utilize a blade that was custom made by hand for me by a local knife smith.
In summary, a chef with great knife skills can cut with any blade as long as it has an edge. At the end of the day, it all boils down to personal preference.
