Ergo Square Non-stick Bone Folder by Bonefolder

Very smooth, does not leave marks, and does not damage the paper. The angled tip helps a lot, I have the straight one too which is just as nice, but if you were only going to buy one of them, I would go with this one. Very helpful for origami.

They're not made of bone, and the plastic is too soft! I was doing origami with magazine paper, after a few times gliding this bone folder along the folded edges, the edge of the bone folder is dinged up, not straight anymore! For the price I paid, it's totally NOT worth it!

I would have given it a 5 star if it wasn't so expensive.

I finally broke down and bought this, and it's worth every penny. It works so much better than real bone or plastic. No paper shine, and less effort. Yes, the non-stick "bone" folders ARE all they're cracked up to be.

Excellent crafting tool! While the price may seem high, the quality of this bone folder definitely made it a worthwhile purchase for me.

Works quite nicely and cleanly. I’m taking time getting adjusted to the feel of it in my hand.

$18.99 plus shipping and tax seem like a lot but I will soon forget the cost of this excellent tool. Dried glue and acrylic gel don't ruin its smooth surface the way they do with my other bone folder. I use both the beveled and rounded edges of this thoughtfully-designed burnisher, and the point is very useful, too. I will not willingly spend a day working without it.

I haven't tried it for scoring, but it cannot be beat for burnishing...it covers a wider area and is easier to hold than the usual slender bone folder.
