The one rule of knife steel
Higher edge retention almost always means harder to sharpen and (often) more brittle. A Maxamet blade holds an edge for ages but chips and fights the stone; MagnaCut is celebrated precisely because it balances all four properties unusually well. Decide what you'll actually do with the knife first.
