Well, there is no end to the tools you can have and use. For a bottom like that, I would prefer a negative rake scraper. You can do a good job with a regular scraper as well, which may work better if you hone off the burr. I would want one that has a straight edge more than a rounded edge, more like an L but with an 80 degree angle rather than the 90 degree one as shown. This allows you to get a crisp edge in the corner/transition area.
