I have carried the knife for a few weeks now. It is a very stout, well built knife. Carbon fiber does reduce the weight and adds nice eye appeal. I saw a reviewer mention the blade rusting after a day’s use. I have not experienced this. I found the blade easy to open and close. But, for those wishing to adjust the blade action, my knife came with a torx tool which can be used to loosen or tighten the blade action at the pivot screw. I am quite pleased with this knife.
