    The card stock one think it was Best steels for edge retention. Graph showed thinner the edge grind more cards can cut. I could tell you that all the years in front of cutting boards. Grind is everything. It was good to see it on a graph.

    Slicing lemons with pocket knives not the best blade to test with. Again thin grind carbon knives can slice lemons quite a while slicing through the seeds instead of displacing them.

    Have watched NHK world on Japanese limes slicing with carbon super sharp blades clean cuts through the seeds. Acidic foods dulling knives is exaggerated again it is more about grind & edge sharpness.

    One thing is Knife Steel Nerds threads I always have to check it out. No matter if I understand it all or not.

    I did this with kitchen knives to see what guys in the kitchen should expect. The carbons were very informative as the difference between a wipe and just letting the knife rest with water/moist while getting other minor stuff done, was quite important. If you wipe the blade, there is a very little chance for rust to take over fast. If not, even in a couple of minutes bad things started to happen to new knives.
    But rust would take over stainless as well. I saw it just days ago. And a test like this will give an understanding on the matter. Buying something that's stainless does not make you completely forget about maintenance and such alloys will be affected, some faster than imagined maybe.

    I find it funny when I go to friends or families houses and they have a stainless knife or dinnerware that has a little rust or staining on it. They then proclaim, "How can this be rusting, it's 'stainless'!" I like to explain to them that "you're right, it is 'stainLESS' not 'stainPROOF'."

    At risk of being shot down for being off topic, this reminds me that there are two kinds of people: those who can extrapolate from incomplete data ...

    Anyway, always an education to read Larrin's posts. Thank you, Larrin!
