I just received this yesterday and have been playing with it alot. I really like this knife. The blade and the handle make the knife feel "big" even though the blade is only about 3.5 inches. The weight of the knife is biased toward the blade, making nice snap opening. The grinds of the blade are not quite symmetrical but not bad and the blade was the sharpest out of box of all the BM's I've owned. The Noryl handles are grippy and are light because of the partial nested liners. Even though the knife feels "big", its not really heavy. The finish on the blade is interesting also. It appears that the blade was stonewashed and then satin finished overtop so depending upon what angle you look at the blade, it appears to be stonewashed one way and satin finished another. The only real annoyance I've found with the 550 is that when you snap the blade open hard, the lock sticks and harder to disengage. I've not had this problems with my 3 other axis locks, 2 being 940's and one being a 705. Overall, a thumbs up. BTW, if anybody else has had similar problems with the axis lock sticking, please feel free to comment if you have found a remedy.
