• Tang - is the portion of the blade that extends
into the knife’s handle. A full tang that runs
through the entire length of the knife handle
contributes strength and durability to the knife.
For this reason, knives meant for heavy use,
such as French knives and cleavers, should
have a full tang.
• Paring knives, utility knives, or other knives used
for lighter work may have a partial tang.
6. Knife ConstructionKnife Construction
• Handle The knife handle can be made from
hardwoods, such as walnut or rosewood, or
other materials, such as plastic or vinyl. When
choosing a knife, consider the feel and fit of the
handle.
• Knives are held for long periods of time, so the
handle must fit comfortably in the hand.
• A handle that is either too small or too large can
be uncomfortable to hold.
7. Knife ConstructionKnife Construction
• Rivet Metal rivets hold the tang in the handle.
Rivets should lie smooth and flat against the
handle to prevent rubbing and irritation against
the hand. They should also be flush with the
surface so that there are no crevices in which
dirt or microorganisms can collect.
• Bolster The shank, or bolster, is the metal point
on the knife where the blade and handle meet.
• Although not all knives have a bolster, those that
do are very strong and durable. The bolster also
• helps block food particles from entering the
space between the tang and the knife handle.
