Here are some pictures of a knife bought used some time ago. It was pretty beaten up, but I decided to give it a go. Very happy I did. Now, in its current state (I haven’t cared to make large modifications) it has a somewhat unusual profile which makes me wonder; how did it once look? What was the original profile? It is approx 280 mm. You see a bit of overgrind here that I have neglected. Marks from a previous owner, maybe? My own uneducated guess or hypothesis is that this knife had a more standard Gyuto profile, with a higher heel, and that it has been worn down through use (it looks like a classic overgrind due to excessive use of honing rod). But this is pure speculation and it would be fun to know what you guys think. Purely for the sake of satisying an intellectual curiosity.
