I like using a sharp knife for a scraper. I have tried store bought scapers, thick pieces of glass, and several different knives until I got a couple that I really like. I do finer stuff with a little schrade pocket knife and my main wood removal with a broken blade american angler filet knife or an old hickory kitchen knife. I have to touch them up with a file and whetstone now and then, but you have to sharpen store bought scrapers too. A sharp knife held at a right angle to your work and used like a scraper will really curl up some wood. Somebody else mentioned using a buck knife. I have one of those that makes a good scraper too. I think you just have to find what works for you.
