Well...according to some....there are no cons to a Bark River. They are the finest edged tools in the entire history of edged tooldom.
They are capable of making a very good, very well designed knife. But they have cranked out so many models and variants of each model that it seems their primary design concern is making the rabid collector Barkite market happy. Also, they are capable of cranking out epic fails. They will fix the epic fails they have sold, and credit it to their "great customer service"...but that doesn't quite make sense to me. Get it right the first time.
If you can get past the personalities of the primary parties involved at BRK, and the history of those personalities and their products (I cannot), or if you don't know/care about that stuff...then there are some good knives in there somewhere.
