There are lots of times when you can use a nice scraper in the shop. They are great for removing sticky labels, cleaning up paint, or even removing laser-splattered prepunched holes in thick aluminum stock. The problem with using any blade on aluminum, however, is that the sharp corners of a single-edge razor blade will leave scratches. But not if you take a few seconds to round them off on your grinding wheel. Use real light pressure and just a few touches. Now your blade will be effective and not leave marks in your work!
