These knives have seen plenty of use over several years. Some have a slight patina but all look quite nice still. In general people will treat an item according to the value they place upon it.
many of these knives are over 35 years old. most are over 20 years old (just a few newer, and im not even showing the really newer ones - like within 5 years). Almost all are not stainless.
they have been through me as a single person who thought he could keep care of everything in immaculate condition. they have seen a family raised, with early mornings, late nights, cooking, then cleaning the kitchen after working an entire day, putting the kids to bed, then finally cleaning up when I could barely keep my eyes open, much less making sure I only reached for a clean, lintless cloth, when the closest thing within reach with soap on it was a green scrubby. then rinse and repeat - for 35 years. You can care about something, yet not always be able to meet even your own expectations.
My point is that you can state the "ideal" way to take care of a knife, but for you, and especially for your recipients of your product (whether it be customer, family, or friend), you can not define the conditions, and time and attention, that life allows you, or them, to pay to keeping those knives in pristine condition. Not going to happen, unless that person has WAY too much free time to do nothing but take care of a knife - in which case they are more than welcome to their lonely life. so ... how much is it worth to you making that knife pristine and "perfect" out the door, if in a week or a couple months it is going to pick up scratches or discolorations that it took you, as a maker, loads of effort to eliminate??????
Please keep in mind that this is coming from a knife-nerd of 40 years and running strong....
