Which term is used when describing a wound created by a sharp object that produces a long, deep cut?

The term used to describe a wound created by a sharp object that results in a long, deep cut is "incision." Incisions occur when a sharp instrument, like a knife or glass shard, cuts through the skin or tissue in a clean, straight line. This type of wound is characterized by well-defined edges and may penetrate deeply into tissues, which can lead to significant bleeding depending on the location and depth of the cut.

The other terms indicate different types of injuries. A laceration typically refers to a tear or irregular cut caused by blunt force trauma or an object that does not have a sharpened edge, and thus does not create the clean, precise edges typical of an incision. A chop wound generally results from a heavy, sharp object that creates a deep and often gaping wound but may not necessarily conform to the characteristics of an incision. Lastly, a contusion is a bruise resulting from blunt force trauma that does not break the skin, thus differing significantly from a cut or incision.
