I purchased a new Boker Anso 67. I love the style; however, I am a bit disapointed by its operation. I cannot get it to open buttery smooth. I have less expensive Spyderco's that open much smoother without any blade wobble - and the Spyderco Chockwe is smooth as silk. I greased up the 67 in a variety of ways and that does not seem to help. And when I loosen the pivot screw to where it is really smooth, I get blade play - so I have to tighten it up to remove the blade play, and then it is sticky. Any suggestions on how to make the Anso 67 smoother?
