I have had a few ZT's. I got a gifted 0770 since I know someone at ZT. I liked the weight but not the blade shape. Then I got a 0350. I liked the blade but not the weight. My latest is the 0357. I love it. CPM 20CV steel. Lightweight. The little concave back of the blade fits my thumb perfectly when I want to choke up. It's my EDC now. I'll admit that it doesn't look the best, but it sure feels great in my hand.
