Accepted Answer

The blade is the cutting portion of a knife and is usually tapered to a point, through a belly (mid) region before connecting to the handle. The spine is the opposite side of the blade, the ricasso refers to the flat unsharpened portion of blade, and the guard is the piece that separates the handle from the blade to protect the hand.

Question 2

The _____ is the dull edge of the blade of the knife.&#10;A) Spine&#10;B) Blade&#10;C) Ricasso&#10;D) Guard

Accepted Answer

The spine of the blade refers to the top, thicker edge of the blade that runs parallel to the blade's edge. It is not sharp and is used to apply pressure during cutting.

Question 3

The _____ is a dull piece of metal that projects at right angles from the handle and blade and serves as a protective device preventing the hand from sliding down onto the blade during use.&#10;A) Spine&#10;B) Guard&#10;C) Blade&#10;D) Ricasso

Accepted Answer

The guard is a protective device that prevents the hand from sliding down onto the blade. The spine is the top of the blade opposite to the edge, the blade is the cutting edge of the tool, and the ricasso is the unsharpened part of the blade near the handle.

Question 4

The _____ forms the grip area of the knife.&#10;A) Hilt&#10;B) Guard&#10;C) Handle&#10;D) Blade

Accepted Answer

The handle is the part of the knife that the user holds onto and provides the grip for the knife. The hilt is typically found on swords and is a guard to keep the user's hand from sliding onto the blade. The guard is not typically found on knives, and the blade is the sharp portion of the knife used for cutting.

Question 5

__________ are deeper than they are long.&#10;A) Incised wounds&#10;B) Puncture wounds&#10;C) Slash wounds&#10;D) Stab wounds

Accepted Answer

Stab wounds are deeper than they are long. They are caused by a sharp object being thrust into the skin and tissue, creating a puncture wound that is deeper than it is wide.

Question 6

____________ measure longer than they are deep.&#10;A) Stab wounds&#10;B) Incised wounds&#10;C) Puncture wounds&#10;D) Abrasions

Accepted Answer

Incised wounds are caused by a sharp-edged object and are longer than they are deep. Stab wounds, on the other hand, are deeper than they are long, while puncture wounds are narrow and deep. Abrasions are superficial injuries caused by rubbing or scraping against a rough surface. Therefore, the best choice is B - incised wounds.

Question 7

___________contain abraded margins, have small strands of tissue extending between the edges of the wound, and tend to have irregular margins.&#10;A) Lacerations&#10;B) Incisions&#10;C) Contusions&#10;D) Avulsions

Accepted Answer

Lacerations are caused by a tearing or crushing force and have irregular, abraded margins with strands of tissue extending between the edges of the wound. Incisions are caused by a sharp object and have clean, straight margins. Contusions are bruises caused by blunt force trauma and do not necessarily have visible wounds. Avulsions involve the tearing away of tissue and may have irregular or clean margins depending on the mechanism of injury.

Question 8

Sharp force injury wounds are measured in 3 dimensions:&#10;A) Length, width, circumference&#10;B) Length, width, centimeters&#10;C) Width, depth, circumference&#10;D) Length, width, depth

Accepted Answer

Sharp force injury wounds are measured in three dimensions: length, width, and depth. The depth is important to determine the severity and potential damage to underlying structures. Circumference or diameter is not typically measured in sharp force injuries. Centimeters are a unit of measurement and not a dimension. Therefore, the best choice is D) Length, width, depth.
