The two blades a quite far apart. I would consider the 711 the more versatile of the two.
I have both, but the 711 is my go to camp-/hard use knife.
The 1311 however is one awesome blade, so if you can get both, why not?
Thank you for telling your opinion. I really appreciate it. I just ordered my 711 tanker grey. 1311 is probably my next purchase. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
