Pocket Knife

‘A man without a knife is a man without a life.’

A pocket knife is a knife, that sometimes has other blades, that can be easily stored in a pocket, as the blade or blades fold into a holder or handle.
A ‘pocket knife’ has also been known as a ‘spring knife’, ‘penny knife’, ‘jackknife’, ‘jack-knife’, ‘farmers knife’, ‘peasant knife’, ‘sodbuster knife’ and a ‘folding knife’.
Pocket knife blades generally range from 5 to 15 centimetres (2 to 6 inches) in length, and are usually made of steel and have a plastic, metal, or wooden handle or holder.
A pocket knife has multiple uses, and can be used for opening items, cutting items or for self defence, among others.
Basic pocket knives have been produced for at least two thousand years, and became more commonly available in the 1700s due to the Industrial Revolution in Britain, as well as more affordable.

Pocket knives became popular among farmers and gardeners of the 1800s and 1900s, due to the knife’s cheapness and small size.
Pocket knife blades generally do not lock in place, but, when opened, are stable, sometimes due to a spring.
A pocket knife is typically opened using one’s fingers or fingernails, and they often have small grooves for fingernails to slot into.
In some countries there are restrictions regarding the use, or having in one’s possession, a pocket knife, and in the United Kingdom one can not be carried publicly, if the blade is over 7.6 centimetres (3 inches), although there are exceptions.
Pocket knives are often produced as multi-tools, meaning that they are not limited to blades, and one pocket knife can include a number of blades, as well as tweezers, scissors, corkscrew, screwdriver, saw, bottle opener and more.
