it seems clear he means that they break it with their hands, as opposed to using a metal knife; just as metal implements (similar to weapons) were not allowed to be used in making the Mizbayach.
Fievel,
Thank you for the explanation. However, I fail to see the analogy. The bread isn’t compared to the Altar, the table itself is. Indeed, items brought on the Altar had metal involved in their processing (the knife for schechita, for starters). For the analogy to be true, they would be okay to use a knife on the bread, but have to ensure that their tables aren’t made via a process involving metal.
