Blades are the portion of either a tool or a machine, consisting of an edge specifically designed to cut, puncture, slash, chop, stab, slice, or even scrape either materials or surfaces. Blades are mostly created by using a metal such as steel, but can also be made from flint or ceramic. Despite the fact that blades are principally used in the preparation of food, by chopping or slicing it, it's not uncommon for blades to be used as weapons in order to stop the behavior of an attacker by either puncturing a blood vessel or severing a muscle. There are a variety of blade shapes available, some of the most common being listed below.
Straight-back blades are among the most common types of blades. Featuring a flat back, a curving edge, and a dull back, these allow the wielder to concentrate force by using all of his fingers. Because the curve at the end concentrates force on a smaller area, cutting, chopping and slicing with this knife is easier than most others.
A trailing-point knife features a back edge curving upward, hence it is also known as a curved blade. This allows a smaller knife to have a larger curve on its back edge. The primary use for these types of knives is slicing or slashing. Having an upward curve at the end provides a larger cutting area, a common feature on skinning knives.
A symmetrically shaped blade with a centerline alignment along the blade's long axis is known as a spear-point blade. Generally, these blades come double edged, with the strongest blade point being the spear point. This design is also common among daggers. Occasionally, the term spear-point is confusingly used to describe single edged blades with a lack of a central spine, such as a pen knife, formerly used for the sharpening of writing quills. Nowadays, pen knife may also be used to refer to the blade of modern pocket knives.
Needle-point blades have a very sharp acuminated point, frequently found on daggers like the stiletto, which possessed no sharp edges, and the Fairbairn fighting knife. Because of its long and narrow point, friction is reduced while the penetrative capabilities of the blade are increased. If the needle point of the knife is reinforced with a 'T' section, it's called a reinforced tip. One such example of a reinforced tip knife is the pesh kabz.
