I did the same thing to my Hawk 226 last week. When I had it apart I noticed the wedge was rounded over a lot. I rubbed both sides of it on some sandpaper on a board and flattened it back out. I had been having problems holding tension on the blade and that seems to have cured it. I did notice the part of the arm the wedge sets in isn't as sharp a v as it once was so someday I will send it back to Bushton and have them rebuild it.
