Hi Im new here first post. I just received myCRKT Natural today, its a very nice knife,except for one problem,it is extremly stiff to open with one hand on the thumbscrew. I loosened the pivot screw to a point where I could open it,but the blade then has to much side play when locked up.I called CRKT and they said to send it back for replacement. So I will see what happens? Anyone else have this problem out of the box? the pivot screw was so loose I would have surely lost if I tried to use it that way. Anyhow ill let you know how it works out when its returned. sabre67
