A Bowie knife is a style of fixed-blade knife first popularized by Colonel James "Jim" Bowie in the early 19th
Century. It was first made by James Black, although its common use refers to any large sheath knife with a clip
point. This style of tip was used in some of the american M-1 bayonets during WWII. It is also used in
some of the modern military fighting knives.
A characteristic of the Bolo blade is that both curves and widens at its tip. This moves the centre of
gravity as far forward as possible, giving the knife extra momentum for chopping action.
The stiletto type consists of a double edge blade that tapers down from the base into a very fine
point. The thickness of the blade is fairly thin. It is meant for light duty or for cutting flesh
in a knife fight. sometimes it is used simply for its aesthetic value. Such is the case with some
of the German WWII daggers.
| Single edge
A single edge blade is one where there is only one side that has a cutting edge. The opposite
side is normally thicker and flat. This blade is used in many of the bayonets of the world.
one advantage of having a blunt edge is that pressure can be applied on it to help the knife
cut through thicker or tough material.
| Double edge
A double edge blade is one where the cutting edge resides on both sides. Most fighting knives
are built with double edge blades because the slashing motion can be applied in two directions.
That is to say that in a knife fight, if a slashing motion is applied as the attacker steps forward,
it can also be executed as the attacker steps back, without having to change the direction of the blade.
Double edge weapons are banned in certain countries.
| Serrated blade
A serrated blade is a type of blade used on saws and on some knives or scissors. It is also known as
a dentated or toothed blade.
A serrated blade has a cutting edge that has many small points of contact with the material being cut.
By having less contact area than a smooth blade, the applied force at each point of contact is relatively
greater and the points of contact are at a sharper angle to the material being cut. This causes a cutting
action that involves many small splits in the surface of the material being cut, which cumulatively serve
to cut the material along the line of the blade.
