My husband heated bread up in a fleishig oven and straight from the oven used a pareve knife to cut up his very hot bread. Is the knife treif?
The knife is definitely not treif, in the worst event it would be fleishig. If the bread was put in the oven on a rack that was dirty from fleishig oil, the bread will not make the knife that cut it fleishig. Therefore, you knife is still pareve.
