Nail puller called "goat foot"

This puller is used to pull out nails and staples, to loosen upholstery and parts of upholstery with fastening clips. It can be used to pull out anything that is embedded in a gap or perforation and that needs to be removed safely without damaging the surrounding material. It is a metal rod or lever that has a hook or a narrowed shape resembling a „foot" at one end. This hook or notch is designed to be caught by an object, such as a screw, wrench, or other component. The other end of the puller is often equipped with a comfortable grip or metal handle for better handling.
It is used in workshops, the automotive industry, engineering, and other technical industries where small components need to be handled.

A puller is not a screwdriver, but it can have a similar function in some cases when it comes to removing or manipulating screws. The main difference is that a screwdriver is a tool designed to turn screws or other fasteners. It has a fixed tip that fits into the groove of a screw, either flat or cross-shaped, and allows it to be screwed in or out. A screwdriver has a pry function. In some cases, if a screw is stuck or cannot be unscrewed in the usual way, a screwdriver can be used to "pull" or loosen it, thus replacing the function of a screwdriver to some extent, but it is not a direct replacement.

There are several types of pullers, which differ in their shape, construction and specific purpose of use:

1. Classic puller - a tool with a straight fixed handle, a bent hook at one end
2. With a hammer end - the hammer end allows you to use the tool as a lever for gentler blows to loosen components
3. With a telescopic handle - this type can adjust the length as needed, ideal for situations where greater prying force or reach to hard-to-reach places is needed
4. With an ergonomic grip - designed for more comfortable work, especially during long-term use
