Welcome to AAPK! There are a number of experienced well regarded knife mechanics here who can likely repair your knife. You haven’t said what it needs, but I recommend you go to the Knife Repair and Restoration section here: viewforum.php?f=37
. Read through the posts there and then send a PM to one or more of the members who post there about knife repair. Members like Elvis, orvet, muskrat man, and several others would be a good starting place. They’re all good, and therefore they probably have a backlog of work so you’ll need to be patient.
