I enjoy working with paper; I use a steel burnisher and a bone folder to make crisp folds. I wanted to add some odd shape burnishers to my tool box. Making some out of stone (agate) fits the bill. Having a few agates lying around, I made different sizes and shapes. This is what I wanted to share in this instructables.
Agates that I use can be found in Michigan. I tell people to look for a stone that looks like a potatoe. You can hold them up to a strong light to see what is inside as far as patterns. For this application of making burnishers, I can use almost any part of the agate. Agates are very hard and polish to a very smooth finish. I use a large diamond saw to cut the agate into slabs.
