A Provo Craft Bone Folder is a must have tool for every paper crafter. It's smooth rounded edges are perfect for scoring paper to help make crisp, clean and professional looking folds. It's also an excellent tool to use when you need to smooth/press down paper pieces while adhering to surfaces to avoid wrinkles or creases. A great reasonably priced little tool!
I was having a problem with some of my cardstock breaking at the fold on my cards with a different bone folder I was using, but no longer have that problem since I bought this one. It works great! A really good buy for the money too...
Works very well for folding papers (no more using your fingernail!). Also great for creasing or rub ons.
