    Sharpening a Heiji Gyuto...

    Guys

    I just received a heiji gyuto (240mm) yesterday! This thing is a work of art and what I thought the mizuno gyuto would be but simply wasn't. Don't get me wrong the mizuno is awesome but its a totally different knife than this even though they have a lot in common: wide bevels, flat profile, great steel, not a laser, great cutters.

    Here's my question: how do you guys particularly tk59 and Peco sharpen yours?

    Seeing as it takes a nod from single bevel knives with these large wide bevels but on both sides are you basically hamaguriba-ing it on both sides or are you just flattening down the edge of these bevels till a burr forms and deburring and polishing?

    thanks folks

    i do the shinogi line down, the lift up a tiny bit and do the half-way to the edge thing. Then i blend them. If i end up making it really thin, i micro it.

    So no convexing of the edge then, keep the bevel flat? I mean obviously freehanding it will make this happen a little bit but you aren't deliberately clamshelling it on both sides right?

    no, i blend them... but hamaguri edge is not a very convex one... its very mellow. What you do is sharpen from the shinogi line down first. You dont need to hit the edge here. Then you lift up a very tiny bit, so you are sharpening from about 1/2 way up the bevel to the edge (forming a burr). Then, you pick the place where the two bevels meet, and sharpen while very slightly rocking in that area. Thats hamaguri.

    Jon, when you lift the knife a bit to hit the edge, do you end up abrading all of the core steel? When I've tried this on knives with wide bevels, I usually end up only hitting about half of the core steel. I wonder if I need to lift less, but I thought I was only lifting a tiny bit.

    yeah... i end up hitting some of the cladding and all of the core usually. Its each bevel is about 1/2 of the whole. The angle change is very slight. Use sharpie and play around with it a bit... i'm sure you'll get it pretty easily.

    Cool, I'll have to try it out again. Thanks for the tip on the sharpie. I'd forgotten about that trick.

    For me, in order to keep Zakuri pretty, I do shinogi line to lamination line and lamination line to edge, and blend them. This is pretty much how I sharpen my single bevel knives too. The real pain is the back/left hand side, for me a right hander. Just can't keep my hands steady enough when switching side.

    Using a good soft stone, like Takashima from Jon helps making the process going more smoothly.
