There is a striking similarity of a food preparation and a knife making process. You have ingredients, maker's technique, cooking (heat treating) temperatures, cook (soak) time, food presentation (look of a knife), etc.
It took me 3 years to fine-tune the process (I got a lot of help form Devin and folks on this forum with ideas and feedback). People write to me and ask if they can apprentice or offer to pay for teaching them how to make knives. There are certain things I would show, but things that took me a long time to arrive at, but I could teach in one day, NO. I turn down most of the requests, partially because for a lack of time. If I see that the person is putting an effort, I would at least point him in a right direction, but I do think, trial and error tests your resolution, is an important component of learning a new skill or craft.
