What is the nail?
The lever principle has been used by a person since the moment he became reasonable. To fall off a stone or a log, to lift a heavy object, to break off a piece of rock - all this requires extraordinary efforts, but with a lever system even a weak person can move a solid cargo. Today, the classic lever is embodied in an instrument such as a scraper-nailer, but the nail-extracting device is present in various tools, for example, in a hammer or mount, and there is also an independent .
Why we started with scrap - it's quite understandable, this lever is anywhere, it's almost impossible to bend it( human weight, at least, it's not enough for it), and the length allows moving objects with a large mass. The reduced version is often used by antisocial elements not for their intended purpose, but for breaking locks.
Yes, in fact, as an independent element, the jigger can be used to open boxes, pick up various objects, it is convenient for them to scratch their backs. In computer games, this tool is effectively used by various characters as weapons.
What do you need to pull out a nail?
There was a time when wooden nails were used, for their use in the boards, they first drilled suitable holes in the diameter and then only in such a simple way joined the individual parts of the structure. However, the nail( a nail made of wood) is almost impossible to pull out, you can not make a mistake. Another thing is metal fasteners with wide hats, they can be picked up by a jerk - a tool with a flattened end, in which a wedge-shaped slit is made, convenient for grasping the nail.
However, to pick up a little, you still need to pull, and how to do it, if the fasteners are tightly compressed with wood fibers or wedged in the depth of the concrete panel? The force of the lever will help, and that is why all the dermatists are made sufficiently long and with a bend near the hook acting as a support. The material plays a role, for the most part, the tools for pulling nails are made of roasted ones, but someone likes a solid titanium nail hammer, whose reliability can be safely avoided.
Everything for the convenience of working with the
tool The modern industry is constantly evolving, new opportunities are opening up to improve the characteristics of tools, including those that require considerable effort, which means that it is convenient to lie in your hand.
In particular, most hammers with an additional function in the form of a jerk for nails are supplied with a rubber grip, due to which they are clamped in the palm of your hands like pouches. For increased durability, the heat treatment of high-carbon steel is also used - ordinary tool material.
When choosing a hammer with a jerk, pay more attention to single-element tools having higher reliability than those whose working part is mounted on a separate handle.
Modern hammers for roofers are interesting, the jerking on them is somewhat modernized. One of the teeth of the "plug" for such a tool is extended and sharpened, allowing one movement to drive it into the wood, freeing hands or stopping the fall of the .A kind of alpenstock, combined with a dumb-bell. However, do not get carried away by the variety of form factors, the main thing in the tool for extracting nails is the flat surface of the blade, put under the bonnet, and its strength.
