[0001] The present disclosure relates to equipment and devices utilized for cutting. More particularly, the present disclosure relates to a knife for slicing and heating of a food item.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Bread and butter is a great combination. Generally, butter is kept in refrigerator or a cool place having low temperatures, in order to avoid degradation of butter, retain its characteristics, freshness, and increase its longevity. However, in the due process, butter may get freezed in the refrigerator and may become hard.
[0004] Spreading of frozen butter over bread is really a tough task. Using of existing equipment, such as, spoon, knife, and other such cutlery, may result in uneven slicing of butter, and may even result in tearing up of the bread when butter is tried to spread over said bread through said equipment. Moreover, frozen butter may not be uniformly spread at the bread, instead it may get scattered here and there in form of small bits and pieces over the bread. Further, spreading of hard and frozen butter may prove to be a cumbersome chore that could consume a great amount of time.
[0005] Therefore, there is a need to provide a solution to overcome above-mentioned problems and aid in easy slicing of the butter and spreading it uniformly over the bread.
