A
cold chisel (originally diamond-chipped) is a chisel tool sometimes composed of
tempered steel, with a strength, shape, and temper suitable for chipping or
cutting cold metal. It is struck with a mallet by hand, or mechanical power.
Diamonds
Diamond
is the hardest naturally occurring material known. Over 70 percent of diamonds
are used for industrial applications, while the rest usually go into
ornamentation. The main utility of ornamentation is the application of
influence on human minds in the attempt to direct them towards particular lines
of labour. This is basically the domain of propaganda. A potent tool used to
direct human activity towards serving the producer’s interests. The main aim of
propaganda is invoking certain emotive reactions such as fear, reverence, demoralization,
bamboozlement, and so forth. The use of diamonds in this may just be a drop in
the ocean but still remains significant in the domain of the diamond industry itself.
Case
of United States
Domestic
Production and Use: In 2019, total domestic primary production of manufactured
industrial diamond bort, grit, and dust and powder was estimated to be 190
million carats with a value of $86 million. There was no domestic production of
stone. One firm in Ohio and one firm in Pennsylvania accounted for all of the
production. At least nine firms produced polycrystalline diamond from diamond
powder. At least two companies recovered used industrial diamond as one of
their principal operations. The major consuming sectors of industrial diamond
are computer chip production; construction; drilling for minerals, natural gas,
and oil; machinery manufacturing; stone cutting and polishing; and
transportation (infrastructure and vehicles). Highway building, milling, and
repair and stone cutting consumed most of the industrial diamond stone. About
99% of U.S. industrial diamond apparent consumption was synthetic industrial
diamond because its quality can be controlled, and its properties can be
customized.
In
2019, China was the world’s leading producer of synthetic industrial diamond,
with annual production exceeding 14.6 billion carats. This is almost a hundred
times the production by united states. U.S. demand for industrial diamond is
likely to continue probably in the construction sector as the United States
continues building, milling, and repairing the nation’s highway system. Industrial
diamond coats the cutting edge of saws used to cut concrete in highway
construction and repair work. Synthetic diamond production far exceeds natural
industrial diamond output. Worldwide production of manufactured industrial
diamond totaled at least 14.6 billion carats in 2019. This is largely
equivalent to Chinese production alone.
The
mining of natural rough diamond is rapidly becoming an endeavour in mere luxury.
Global rough diamond production decreased by 14% during the first two quarters
of 2019 driven by reductions in Botswana and South Africa. Globally, most
natural industrial diamond is produced as a byproduct of mining gem quality
diamond. The bulk of natural rough diamond produce goes only into ornamentation
while a small portion goes into synthetic production for industrial use whereby
billions of carats can be reproduced from a very small amount.
Conclusion
National
development is all about having functional public utilities. These are things
and processes that can be utilized to make human activity easier, more
efficient and effective. The more efficient and effective the utilities, the
greater the impact of that society in being able to survive and express itself
in the world.
