I see the Mutt as a potential "Jack of All" type blade. Not too job specific but good at just about everything. Perhaps one of those "If I could only take one knife with me" deals.
I can see that. I think I'd take the Dogfather or one of my other previously mentioned choppers if I could only have one - I'd rather do small work with a big knife than big work with a smaller knife - but as far as a tactical blade goes, it'll be the DM or my RD7.
