    I was just gifted an Aritsugu Kyoto Gyuto knife from a friend. It was just collecting dust at his house and I ended up inheriting it. Yes I know lucky me, good friend.

    Here's my dilemma and the help I need. My friend has been sharpening this gyuto as a single bevel as that's what he (thinks) it came set as. I'm under the impression that Gyuto, as a western style knife should have a double bevel. If i'm right, and it's been wrongly sharpened as a single bevel, should i take it into a knife professional to get the edge re-set? I'm comfortable sharpening my own set of single bevels, but if this knife hasn't been treated well, i'm thinking starting fresh with a professional is probably a good idea.

    My friend purchased it personally from the Aritsugu store at the Nishiki Market in Kyoto. (Not Aritusugu Tokyo / Tsukiji market).

    Here are some photos of the knife in case this helps with identification.

    A choil shot would be most helpful.
    Most Japanese double-bevelled knives are strongly asymmetric. Right face convexed, left one almost flat, edge off-centered to the left.
    When sharpening you want the right bevel to form a continuous arc with the blade's face, ending at the very edge. As for the left side, all you do is making a small bevel, probably at a much higher angle, to balance friction on both sides and reducing steering as much as you need. Common figures are an angle of 10-12° on the right side, and 15-20° on the left.
    I start sharpening the right side with thinning at the lowest angle. That will abrade from about 1cm (3/8") from the edge if the knife has thickened by some neglect.
    I aim for 0.2mm thickness above the edge, 0.5mm at 5mm from there and 1mm at 1cm.
