I have a Benchmade 707, and my brother just bought a mini presidio, both of our knives have side to side blade play, no matter how much you tighten the pivot screw. My 707 is not to bad but my brothers presidio has a lot of blade play. He is going to send it back. I also recently bought another 707, and it had a lot of issues. The knife had nicks and a pretty bad burr on the blade, and the axis lock was adjusted horribly, it was very loose, and sat crooked when locked, also the g-10 inlay did not sit flush on one side, not even close, it was raised above the scale quite a bit. I returned the 707, and we will see what Benchmade does with the Presidio. I hate to say it because I like Benchmade knives, but the quality control is not that great. I have read many posts about problems related to mine, It seems to be some what common, which is not good. i will say most threads I read were people send the knife back, the problems are fixed, but who wants to buy a knife thinking there is a good chance it will need service. I am just speaking the truth about problems I have seen first hand, i know some people might not like hearing this stuff, but I always like to share real experiences about products. I have pictures of the 707 I might put up some time soon. I have only purchased two Benchmades, and my brother purchased one, all had issues, just being real.
