The quality of the steel in your scraper does indeed matter. It's like any other good cutting tool. The better the steel, the longer the edge will last before you have to sharpen again. The most important thing with a scraper is to get the edge square and sharp to the sides. Once that is achieved, then you can roll a good bur. The bur is like a small hook that shaves the wood. Once you use a good, properly sharpened scraper, you will turn your nose up at lesser tools. Highland Woodworking has a good rectangular scraper for about $8.00.
