Q. If I cut bread with a clean (from the dishwasher) fleishig knife can I eat that bread with cheese?

A. Horav Shlomo Miller’s Shlit”a opinion is that if the fleishig knife is scrubbed, washed and visibly clean it can be used to cut bread to be latter consumed with dairy products.
He related that in his own family, his father zt”l would after cutting the chalah and passing portions to all present, remove the chalah from the fleishig Shabbos table. Later, being careful that hands were clean, they would further cut portions as needed. This was done to permit the remaining chalah for every use.
