I own two Benchmade 710's.........the D2 model is the one that I really beat to hell, and then I have the M2 HS model that I take with me when I need a superior strength steel that holds a fine edge.
While I may be partial since this has been a star in my EDC rotation for MANY years. I don't think there is a single Spyderco out there that can beat it........and I have several. The 710 has a slim profile and carries much smaller than its 3.95" blade size. For someone who prefers to carry a longer, but not fatter, blade, this is a nice bonus. The new steel is supposed to be very good, as well. Most importantly to me, I can also have the blade out of pocket and open the AXIS lock as quick or quicker than many Autos. The lock is super sturdy, and with a blade up right hand carry, I can grab the lock with my index finger and thuimb and flick the knife out as I let go of the lock for a super fast opening.
The 710 has a great shape for all around cutting tasks, has a nice point for more detailed tasks, but would also make a very good defensive knife if the situation arose. I started carrying the 710 while in the military when a few of my buds at JSOC got me one as a gift ( back before I became a knife junkie ). The knife holds well in hammer and saber grips and particularly well in REO ( Icepick or Reverse Edge Out ).
Anyhow, if my input has any value, to any knife collector ( and user ) who doesn't have one, I would recommend getting a 710 over pretty much any production blade in the same price range. It really is a fine blade all around.
Hope this helps.
