I am really torn over the Mutt. It would basically fill the same niche as my Busse NO-E but there is about a $400 price difference right now. And aside from strictly controlled tests I don't think I would ever be able to tell the difference performance wise. Other than corrosion. But I take care of my knives so that's not an issue.
I think you know what you got to do. Make the NO-E a safe queen because it will be worth about $100 more if you don't use it, get the DM for $70 and wail on it till your spent.
