Hey Bud - I opened a show for Allen Block some years ago at a little coffee house in Massachusetts. When one of Allen's banjo tuners started slipping he asked the audience if someone had a screwdriver or a knife blade. I handed him my pocket knife and he was floored becasue it was a Barlow knife. He went on about the song, and was so impressed to have finally seen a real life Barlow knife - I gave it to him. Years later I was at a Folk Festival in New Hampshire and as I walked up to the seating area I heard the fellow onstage introducing this song, and he told the tale of someone givng him the knife; it was Allen again. I haven't seen him since.
