Like others have said, Starting out I just used whatever the big box stores sold. But then after Joining this site and others, doing a little reading, I learned about Mikes Workshop and the Flying Dutchman blades. Absolutely love the Ultra Reverse and the Polar Blades. I use 1 through 7 in the UR and 2/0 through 7 in the Polar. Cutting name plates, pictures, and Intarsia.
