    In 2014 I bought the 120mm denka.out of the box it was extremely sharp.but after some time I decided it needed sharpening,but I was not skilled and used an adjustable angle guide which I used for all of my knives giving a v edge.I found that this was not good for this knife and after trying(for much too long)I had ground alot of steel away and became put the knife away realizing that I need to learn freehand sharpening.
    I am still learning to sharpen but once I made a convex edge on the knife there was no more chipping of the edge. I was so happy and the denka is now one of my most used knives,and will even cut through pumpkin skin without rolling or chipping the edge.the little of the hard steel left has become stained but has never rusted.if only I had learned to sharpen earlier...So I would like to say thank you Mr Teruyasu for the craftsmanship and skills that goes into the making of these knives and I will still have many years of use from it
    Regards David
