I'm using a Bidex Carl 12 inch rotary. My husband had it in his office when I started scraping. I ordered 4 new blades and I think that cost $30. The issue with it is there is a cutting service under the blade that wears out and has to be replaced periodically like the blade does. You can turn it over and use both sides. Once it is worn out and has a crevasse in it, it will cut just slightly off. That part is not as easy to find. So now I want the Fiskars, but I'm stuck with extra blades.
