I have the yellow orbital sharpener and it works fine but there is no help for nicks in the blade. I like the Olfa ergonomic cutters the best. There are quick change cutters, save your money, it isn't that hard to change a blade. Fiskars is not that comfortable for me to use. I have arthritis and degenerative disc issues in my right hand. Prolonged use of anything that requires using my hand/wrist can result in a lot of discomfort. Joann's runs sales on them or use a coupon. I have tried Clover as well, not crazy about their cutter either. I did buy a titanium blade and cutter, forgot the brand name and I did like it, I like using 60mm blades. The bigger the better for me.
