I am looking at both of these blades and really they can not be any more different. But I want to get a new knife and really like both of these models. I have the D2 para but I have always wanted a Military but I really like the Stretch. Both are FFG and one is S30V and the other is VG10. G-10 vs FRN and lock back and Liner lock. Or should I just get both and be done with it.
