These are my bonefolders. I use them all occasionally, but the one on the very top, and the completely round one got used the most. I once had another really big one for folding big sheets of paper, but I hardly ever used it, and when I wanted to take the picture I couldn’t find it anymore.
Recently I bought the one at the bottom, and it is made from plastic. I was skeptical when I saw it, but it was cheap, and so I decided to give it a try. So it is not one of the expensive teflon folders but a very cheap plastic thing. With an odd shape, too.
After a day of usage I love it! The shape is actually nice, and the folder lies neatly in my hand. And because it is plastic, it doesn’t give this typical bonefolder shine on the creased fold.
But why, I have begun to ask myself, is it apparently essential for the functioning of a bonefolder that it has this tiny hole at the back? Anyone knows why it is there, and what its function is?
