I finally got a benchmade 710 last week and all I can say is that I am now a huge fan of D2 tool steel. I was skeptical about it at first reading on how it wasn't stainless and seeing somebody's on youtube that got stained but I learned that with a little proper care it is one of my top favorite steels. I like it far better than 154 CM,VG-10, 8Cr13MoV,440 C, 1095, etc. I do have one concern though and that is my axis lock is sort of loose. I can push it down further on one side tan the other in the closed position and it wobbles a bit if I take two fingers and move it up and down. Is a loose axis lock something to worry about? Is it normal? Btw, I bought it from Grand Prarie Knives, those guys are more than helpful and curtious to their customers.
