Alright, I actually give this knife 2 stars, but I wish there was a "Zero Stars" option just to balance out all of these 5-star reviews. Apparently this is the first knife some of these people have ever held.
In the open/locked position, the blade is loose. Right out of the box! It's not huge but it is noticable, and on a knife as bulky and heavy as this monster I expect better. Speaking of bulkiness, it's too big to be my daily carry, and I wear loose clothing with big pockets. They could have slimmed down the handle significantly; it's not like the thing is flimsy. (Although the nylon handle is not very grippy. This makes it easier to slide in and out of your pocket, but I would not want to use this knife with wet/oily/greasy hands.)
The advantages of this knife are durability and ease of use (unless you're a lefty). The blade seems to hold an edge well and it is pretty thick -- no risk of bending or breaking it. The SAT technology is great; it opens the blade quickly and it ALWAYS engages the lock. No funny business. Also it has not yet opened when I DIDN'T want it to open (in a pocket, for example). The safety lock is a nice feature but I doubt I'll ever need it.
My only beef with the mechanical operation is the lock release knob. In the closed position it roams freely througout the slot, and when the blade is locked open it still has significant play. This doesn't really have any negative effects on the usability, it just seems sloppy. Also, the knob is only on one side, so left-handed knife users will not get the intended ergonomic ease of operation.
In summary: not worth the $75 MSRP, you can def get a better knife for that kind of money. I scored it on SAC for $30, so I'm happy to leave it in my car's emergency kit because (1) weight and space aren't at a premium and (2) I think it will be dependable even after years of rumbling around in there.
