I have a 2014 Carbon Knight that I bought December 2015, within a month I noticed the serving on the cables fraying around the cams. I emailed Bowtech they advised me to take bow to store I bought it and have them look at it. Scheels in Omaha NE just redid the serving. After awhile it started fraying a little again. Move on I got a custom string, and last night when shooting I noticed what you can see in the pictures. Bowtech said again just take back to where I bought it, maybe might need a new cam, possible burrs or something. Archery season in Missouri where I hunt opens 09/15 Does this look in the least bit safe to use? FYI Extreme Bowstrings, got Fury strings, amazing stuff, great guy at Extreme Bowstrings, I am not affiliated with them in any way shape or form but I am very impressed with him, his work, and his help via email with the above situation.
