can't decide which one would be best. Was stuck on the 710 at first but then read it can be difficult to sharpen the slight recurve, already have an edge pro, would this sharpen the recurve easily if the knife dulls? Out of the 3, which would be your first pick? Really like the looks of the 943 but not sure how strong it would be bc the blade looks awfully thin compared to my paramilitary 2, even though i would never use my knife to pry or severely stab a hard surface
