Try goo gone, you can buy it at any auto parts store.

I don't have any info on the knife. A Brother Mason is always searching for "More light in Masonry." To learn more about the history of Masonry and what it is all about. George Washington and many presidents where members as well as General Patton. Many famous statesmen and actors. The history dates back to the building of King Solomons Temple. As far as we know.
