To slice fresh bread, hold knife under very hot water until it is hot. A hot blade will cut the freshest bread into perfectly smooth slices.
To remove the black marks caused by non rubber heals, apply a little squirt of white toothpaste with a soft cloth. Remove toothpaste with a damp cloth.
Another way to remove a black scuff mark from a floor other material is to use a dry papertowel and rub the area (do not dampen it!) or use the 'magic eraser' that hit the markets a few years ago. They both take scuff marks right off.
