No.
But this brings up a difficult and painful topic. I have no way to hone or sharpen it. I possess western type whetstones -- including a pretty pink natural Arkansas -- on which in my youth I ruined the edge of many a fine blade.
Fortunately on the website I saw that Watanabe will resharpen his knives at no cost.* That's the good news. The bad news is that a friend whose kids lived in that country informed me it is illegal to ship knives to Japan. Her son told her: "Don't do that again."
I also noticed on the Watanabe website that waterstones cost more than my knife.
*"After using a long time, when the blade edge is dull, we are going to resharpen again and again. It's free.(the round of shipping your charge.)"
