Update. I sent it in over a month ago. 8 emails and 2 phonecalls later I got a response saying that they have my knife it's not repaired yet and they will need $15 to return it. Still waiting to hear back on what form of payment they will accept.
I will let you guys know how it is when they return it.
I think after two weeks I would have been placing a phone (s) call to find out what was up, and would not have left them alone until I got an answer. (Always send items with shipping confirmation- so you know the date and time delivered)
the $15 is for return shipping, not unreasonable IMO, afterall your are not the original owner.
