I'm a bit confused and am hoping to get some clarification. It has been said that merely tilting the handle upwards on a conventional scraper does not turn it into a negative rake scraper. Furthermore, the contention is that a negative rake scraper requires a small top bevel. It would seem to me that a properly tilted scraper would create the same angle of presentation to the blank that would be achieved with a top bevel. IOW, how does the wood know? All it sees is that angle. It has no idea how many bevels are present.

Case in point. Below is an image of a scraper that Crown is marketing as having a negative rake. Obviously, there is no top bevel. What's the difference between this and tilting a conventional scraper?
