Actually repeated tempering does make the metal harder, and more durable, and allows it take a sharper edge. But it does not make the metal more brittle. It makes it less brittle. This is why the expert Japanese sword makers of yore could make such amazing swords (using repeated tempering). The swords were less brittle, not more brittle. To put it another way making the metal harder doesn't necessarily mean that makes it more brittle, although some materials like certain ceramics are very hard and brittle.
