My mom always used to sing that song to me when I was a kid -
"I know a gal named Boney Maroney,
she's as skinny as a stick of macaroni,
But I love her, and she loves me,
Oh how happy we will be!"
It explains a lot about how my mind has been warped toward a love of corny jokes and puns, and also provides a tenuous link to a post about my new teflon bone folder from Paper Source. When I first began using it, I wasn't sure about it. I tend to use my bone folder for everything from folding, to smoothing paper, to flattening brads - and for some of these jobs, it's just too soft. Well, it's really just too soft for flattening brads - but it works like a dream for folding paper, and smoothing down freshly glued covers and endpapers. The main selling point is that it never leaves a shiny mark - on anything.
Having different bonefolders for different tasks is cool though - one of my bookbinding teachers had a whole arsenal of bonefolders. He even would carve them into different shapes for different tasks. He was a bit of an expert in bookbinding tools, and gave me a great tip - soak your bonefolders in oil to clean and refresh them. It really works well.
In conclusion - I would recommend adding a teflon bone folder to your bookbinding arsenal. No more shine marks!
