Second, is I've had two knives I've had to send into BM, a 810 and a 760, both for blade retention issues, a well documented problem with the 760, neither were fixed and were returned no better than they left. If you can't or won't fix it, at least say so, save me the hassle and cost of returning it. So while others have had good luck with their customer service, I see no point in sending in another knife only to have it returned the same way it went in. I do like that they will send free screws/clips at request.
I have also had a knife returned to me without being fixed. I tried to be ok with it, because the knife had been discontinued for 5+ years and they sent a note along stating that they didn't have the parts to fix it anymore. While that is completely understandable, I sent an email in to their customer service department before sending the knife asking if they would be able to do anything for me since the knife was long discontinued. I got a reply back asking me to send the knife in for them to fix it. I was excited that I was going to be able to get my discontinued knife fixed until I got the actual knife back in the mail. Also, they couldn't fix the knife, but simply sent it back to me with a note saying as much. There was no attempt made by BM to offer me any sort of replacement for my broken knife. Just a note telling me, "tough poopy."
Around that same time, I sent a full sized Griptilian in for lifesharp service. When that knife came back to me it was razor sharp. However, when I sent the knife in it opened extremely smoothly with rock solid lock-up and absolutely no side-to-side play. When I got the knife back, the action was still smooth but there was a large amount of side-to-side play. I tried adjusting the pivot to get rid of the blade play, but if I got the pivot tight enough to remove the play then it was very difficult to open. To achieve the opening action it had when I sent it in, I had to live with a tiny bit of side-to-side play. Just not the kind of service I was expecting when I sent it in to them.
