I received my ZT0200 today (finally). This thing is huge. I got the combo edge and my first impression of the serrations was that they did not feel all that sharp. However after cutting throught the UPS box the knife came in the serrations are plenty sharp. The straight edge of the knife is sharp enough to shave with right out of the box. The overall constuction of the knife is extremely solid, I am very impressed with this knife. I can't believe how thick this liner lock is and it feels really solid. Ken Onion and Kershaw did a really good job on this knife I can't say enough about how much I am impressed with this knife.
