So my Moritaka Deluxe (#2) 270mm gyuto arrived on Monday. It's not sharp. I will have to make it so. Are there any tips on what I should be doing to set the initial edge? I'm thinking a light treatment with the 400k (chosera) at 15* then carry on through the 1000k and 5000k. That should be about it, right? Nothing special to do? Thanks!
