I happened to be in my local cutlery store and while talking to the owner about his honing service, he showed me some new old stock dovos he had found in the stock room. They had been left by his father. That's the back story.

In any case I spotted a Bismark with bone scales and he sold it to me for an insanely low price, stating that's the price my dad had on it and I don't sell them so take it or leave it. needless to say I bought the Bismark and 2 others. So my question is how can I date the Bismark I know Dovo doesn't use bone on them anymore but I don't know when they discontinued this model can anyone help.
thnx emef
