These are used on the outside of a form.Hmm, never thought about using a ceramic hone to raise a burr.... Now, if I can just find that old one I have around the house some where...... I have seen that shear scraper before. Should work fine for the outside of a bowl, but needs a ) nose on the other end for inside of bowls... What is the metal, any one know? M2? M42?

On the outside the square scrapers and angled scrapers are much better at fairing slight imperfections in the curve.While I don't do many hollow forms, I do shear scrape just about every thing. A round nose scraper can go either right or left, so no need to reverse the cutter. I consider a round nose one safer as well. Mostly you keep your handle dropped, which means you can only work on the lower side of the cutter, and can't get up on the tip, which will roll on you, just like a skew will.

Just because one doesn't understand, doesn't mean it isn't so.
