I have always preferred the blade shape of the ZT 0200 to the ZT0301, but it lacks assisted opening. Fortunately, it has a flipper, like my Kershaw JYD 2. I hated the JYD when I first got it because it was too stiff to open one handed. But now that it has broken in, it works very well. The new ZT 0200 was fast opening out of the box, maybe as fast as the 0301. The ZT0200 is every bit as big and heavy as the ZT301, but half the price. It has 154CM steel instead of S30V, but I never had a problem with 154CM.
