    You could etch every blade if you want but it is easier not to mix belts in the long run. A quick muriatic acid dip will show any embedded iron pretty quickly if you are concerned and yes the iron is typically surface only unless welding on the parts

    For the couple of knives I’ve sold I’ve also included write ups. Do you recommend the person oil their aeb-l knives?

    It's entirely up to you the maker.

    As AEB-L is stain resistant, I have never recommended the customers oil their blades. A simple care instruction like "wash in warm soapy water, rinse and wipe dry."

    Seven years of using AEB-L for kitchen knives I have never had any complaints about rust. Even the "fail" builds (yes I have those too) we use in our kitchen have never showed any signs of rust and some are from 2013. My wife, being "quality assurance" will leave them in a pot full of water overnight. Maybe our mineral rich well water doesn't react with steel, but it sure stains the sinks and tubs over time.

    not sure I mentioned it but the water treatment plant process for making potable water can play a part in having stainless develop rust stains. Well water is not a problem while pool water is the worst case scenario

    So, my wife left the aeb-l chef knife I made her out on a dish towel overnight, wet and in contact with other dishes. About 12 hours later there is rust spots where the knife was in contact with other dishes which also meant that water droplets remained at these contact points.

    Is this to be expected?

    She/we have always dried it right away and put it back in the block but it was just one of those nights lol.

    I should note that we are on a well but we have a water softener system which uses salt. The water itself has no salt taste at all like some people’s water I’ve tried with similar systems. I say that to say our system likely has very low amounts of salt in the water.

    Rust spots can happen on stainless steel under the right conditions.

    Small steel particles can get imbedded during grinding and appear as rust spots.

    Clean it up the blade and give it a coating of wax, buff and it should be good for the time being

    Can you advise on the type of wax and how to apply?

    I have used carnuba paste wax on handle and blade.
    You can buff by hand

    Beeswax is another option for the blade and buff with machine

    Hi,

    I wanted to let you guys know about an interesting test that Scott Larimore @seedylotknives on Instagram is doing. He's parked a bunch of different surface ground steel samples 40 miles from the Atlantic Ocean in West Virginia, and is taking pics of them periodically. This shot is after 39 days.
