I agree with Sergiusz. The testing was very useful and it showed just how tough the axis lock is.
If you buy an axis, the last thing you have to worry about is the lockup. It's been out for quite awhile now and I've never read anything bad about it. Mostly what I read is that it's one of the best you can buy.
Benchmade itself is another story. They keep cranking out wickedly attractive knives but QC is another thing. And you may have to resharpen or reprofile an edge, depending on what you plan to use the knife for. If at all possible, handle the knife first before buying. Look it over carefully for smoothness, wobble in the pivot, even grind lines, full edge sharpness, etc. BM QC probably isn't as bad as we all make it out to be but BF people are not your average buyers, being much more knowledgable and particular about their cutlery. But it does pay to learn before you shop.

And so, to all outdoor folks, the knife is the most important item of equipment.
