They are both owned by the same people, Gransfor Bruks being the flagship and Wetterling's being the value line.
From what I have read, they are both of great quality with the Gransfor Bruks models being better in the fit and finish department. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
If you're on a budget, get the Wetterling's and never look back.....
Or just use your 1311 as an axe! <img src="/ubbthreads/images/graemlins/crazy.gif" alt="" />
