When it comes to knifes, I always consider the following:
1. Do you ever sharpen a vegetable peeler? The peeler remains sharp because the blade never touch anything else except food.
2. Sushi chefs have razer sharp knives because they use good knife skills. If you watch carefully, the main part of the bade never touch the cutting board when they cut.
3. Steel is one of the cheapest metals. Stainless steel is also cheap.
4. Tool steel is so hard and so cheap, it is used to make tools to cut other metals. Some knife makers just use cheap files to make very good knifes.
5. Any metal can be make razer sharp. It's meaningless to judge a knife when you have a new razer Sharpe knife .
6. A $1,000 knife can be permanently destroyed in a few seconds if not sharpened carefully by knife sharpeners.
So I make my own knives.
