Obviously both are great. I had a 710 but sold it because I couldnt sharpen it. That has changed and I would really like an axis lock of some kind. These 2 are my first choices. The osbourne models are nice but I'm looking for something a little bigger. Does anyone know of any problems w/ either. I havent held the ares, but my friend still has the 710 and lets me look at it. Also, does the ares come in an all black handle? Some people like a splash of color to their tactical knives, but I find it hard to beat plain black. Also, does the ares have the interchangable pocket clip for left or right side carry, and is it tip up or tip down. I prefer tip up myself but its not as big a issue as being able to swap the clip from left to right. I'm a lefty and thats one reason for the axis fever I recently aquired.
