I sent a used Benchmade Griptillian H20 with older XM-15 steel in for a tuneup. Mind you this was a $40 knife that I just found in my local market and it was a user. It was out of alignment for so long that the blade had lost some of the finish. I sent it in with no box (It didn't come with one) just wrapped in what paper the post office had around. Was I surprised when it came back! New everything, and in a box! Even a new blade in XM-15! They basically replaced everything except the scales and lock. So for $40 (plus $6 one way shipping) I now have a brand new knife that is perfectly centered and scary sharp. Very impressed!
