Just opened my Moritaka Deba (6.5 inch) and I am really, really (well love) both the heft and the look of the knife. So far I have really enjoyed working with all of the Moritaka knives and have had no issues with the bit of extra care carbon steel knives require. I have always thought that the knife should do the work and I merely guide it along and these knives pretty much prove my point.
Thanks for the beautiful knife and the quick sending! (i got the knife sooner than expected and you gotta love that!)
