So I know there is lots of talk about the BK9 sheath. I read the posts on how to remove the insert so that I could heat it up (boiling,heat gun) to remove the rattle. Well I tried and tried to remove the insert and just could not get it out. I have worked on it three separate times and finally got frustrated and cut the sheath to find out the problem. Turns out the insert was actually sewn in to the sheath. I have pictures but no way to post them. I can email to someone that can post the pictures. I have a kydex sheath for the BK9 so I really didn't need the stock sheath. I just wanted to understand and post the problem for future owners that have a hard time removing the insert. Thanks!
