The Different Types of Knives That Are Used as Tools
Knives were one of the first kinds of tools developed by
early humans and although they are most commonly thought of as weapons they are
still used as tools. Take a look at this guide to the most commonly used tool-knives.
Retractable Blade Utility Knife
This is a general-use tool designed to cut materials such as
drywall, cardboard boxes, laminates and plastic. The blade retracts into the body of the knife
for safer operation and storage.
Some models have up to 3 different blade positions for
different cutting depths. Higher-end models have rubber grips and ergonomic
designs for better gripping.
The handle generally unscrews or swivels open to permit
blade changes. Many models have extra blade storage in the handle and some
models have spring-loaded blades that automatically retract when the knife is
released.
Fixed Blade Utility Knife
The blade on these knives locks between the halves of the
knife to provide more blade stability than retractable models. The handle generally unscrews or swivels open
to permit blade changes. As with retractable knives, higher-end models have
rubber grips and ergonomic designs for better gripping. Unlike retractable knives, these knives
accept larger or special-purpose blades that can’t retract into the handle.
Snap Blade Knife
The blade sections snap off (generally between 8 and 13 per
blade) without having to open the tool to change blades. They are generally
used for cutting light- and medium-duty materials such as wallpaper, rubber,
vinyl and leather, or materials with adhesive backing that will stick to the
blade and prevent sharp, accurate cutting.
Carpet Knife
Carpet knives are designed for trimming and cutting carpet
and other flooring materials. Their angular design provides easier access to
hard-to-reach places. Many models feature retractable blades and blade storage
in handle.
The Precision Knife
This is a pencil-sized tool used for precision cutting of
lightweight materials, such as paper or poster board. It is also called a hobby
knife or X-Acto® knife. It is equipped with ultra-sharp blades made from
surgical steel and the blades come in a variety of sizes and in triangle and
curved shapes. These knives contain a built-in chuck to hold and secure the
blades. Some models feature blade storage in the handle.
Cooking Knives
Cooking knives comes in many shapes and sizes and are
designed for specific tasks. Selecting
the knife you need depends on your culinary experience, the style of cooking
you prefer and how much money you wish to spend. Here is a list of the common
types of knives and the basic purpose behind their design:
Boning Knife: It has a 4-5" blade and is a
flexible knife for separating meat from the bone. This knife is more efficient
for this purpose than a rigid knife
Bread Knife: With a 9" blade these knives have sharp,
scalloped blades that “bite” the bread without squashing the loaf.
Chef's Knife: Sporting a 4-12” blade, these versatile
knives serve a variety of purposes but are particularly suited to chopping and
dicing. When buying a chef’s knife you should select a blade length that is
comfortable for you.
Cleaver: With a strong 6" blade the cleaver chops
through bones and joints. You can even use the flat side of the cleaver to
crush peppercorns and other spices.
Fish Filet: It has a 7" blade. This thin, long
blade has great flexibility and is perfectly suited for filleting fish. It is a
superior tool.
Ham Slicer: With a 10" blade it has been
specifically designed for slicing through the unique texture of a ham.
Oriental Cleaver: It has a 7" blade and it's
called a "cleaver" but it's really a fine chopper and dicer of
vegetables, herbs, meats and fruits. It is not to be used to chop bones.
Paring Knife: It has a 3½-4" blade and is the
most commonly used knife in the kitchen. It is used primarily for hand-held
tasks when control is essential. Variations of this knife include the Bird’s
Beak which is designed for peeling small round fruits and vegetables.
Salmon Slicer: It has a 12" blade. This long
thin and exceptionally flexible blade is designed for slicing smoked salmon.
Slicer/Carver:
An 8-10" blade that is used for carving paper-thin slices of meats,
fruits and vegetables. The pointed tip cuts around bones or pieces of melon.
Steak Knife: With a 5" blade this sharp knife
cuts through thick steaks and chops. It
is designed to be an integral part of any place setting.
Tomato/Bagel Knife:
This serrated knife has a 5" blade and is great for cutting
something that's soft on the inside and tough on the outside, like a tomato or
a bagel!
Utility Knife: With
a6" blade it is a cross between a paring and chef's knife. This
all-purpose knife is designed for a variety of everyday tasks.
There you have it. These are the most common knives that we
use as tools in our everyday life.
