I purchased one on impulse while at Lowe's the other day. It had so much blade play in both planes that it went back. Due to all the mostly positive remarks, I went ahead and got a replacement. This second one is definitely more solid, but it still has a little bit of lateral play.
This is my first SOG, assisted or otherwise, and I have to admit that I'm underwhelmed. I don't want this to turn into a vs. thread, but I must say that Kershaw offerings at this price range are much better in all regards except for blade steel. The AO doesn't give the same solid feel and sound compared to an Onion. I also don't like how you can expose a good portion of the tip before the AO kicks in such that it may cause some nasty cuts if in the LF or RR pocket. Of course you could lock it closed, but as someone already mentioned, what's the point on having one on an AO? It defeats the purpose of a knife that's supposed to open quickly.
The skeletonized lock bar is interesting, to say the least. It allows a lockback to have a flipper. While it works okay as a finger guard, I must say the contour of the flipper/guard of comparable Onions provides a more secure grip. It seems SOG used this unique lockback design to appeal to lefties, as the clamshell packaging exclaims that its ambidextrous...but they why have a non-reversible clip? A frame lock would've been better and probably would've reduced the vertical play that I experienced on both examples. Its also easier to close one-handed.
I also don't like SOGs warranty where dissassembly voids the warranty and they want you to send in all repairs. Those that are familiar with Kershaw are aware that you can actually order specific replacement parts for free...its built into their website.
Despite all these gripes, I'm definitely keeping it. Its my first an only SOG and I find the lock bar unique...both qualify worthy of keeping as I like to collect things. I also like the clip, it rides lower that tip-up Onions and it has a different shape. The size is also quite nice, not as big as a Leek, not as small as the Scallion/Chive. It's perfect for most light chores, and like many of you, I usually carry multiple knives. The big reason for me keeping it is its appearance. There's something about it I find attractive. I can't explain it, there's something awkward about it that I like.
