Re: Replaceable Knife Edges, why?
I remember that Australian guy that had the knives Rich mentioned. (Spiro?) I contacted him myself & got no response. I bought 2 sets from Rich, that I still have. I have only ever taken out one knife edge, the straight one, and it was really difficult. I took a sliver or two of the trem body out with it. Not fun. I epoxied the knife back in place but the trem was not the same after that.
I must agree, these were never meant as a replacement part. Least of all by the consumer. Possibly, maybe a factory or tech procedure.
