Tip: forget the bread knife. Just get a normal straight-edged knife and keep it sharp. Once it's through the crust it will cut as well as a bread knife (actually better, because it's easy to keep a straight edge sharpened which you can't say about a serrated edge unless you have a special sharpener) and you won't get a spray of breadcrumbs. Does need to be reasonably sharp, but I'm not talking razor-like. Try it.
