Currently own about a dozen benchmades, 4 microtech's and a few guardian tactical. Decided to give zt a try and purchased the 0770cf, which is ok but not a huge fan, and the 0562cf which I absolutely love. Quality of this one is amazing and so smooth with the ball bearing flipper. Probably my favorite knife so far, just feels so well built and solid as a rock. Think the 0609 is next on my list. Why did I wait so long to try zero tolerance
