kaatne ke aujaar

jese ki chaaku, daraati or hansiya, are wedge-shaped implements that produce a shearing force along a narrow face. Ideally, the edge of the tool needs to be harder than the material being cut or else the blade will become dulled with repeated use. But even resilient tools will require periodic sharpening, which is the process of removing deformation wear from the edge. Also gouges and drill bits.

chalaane vaale aujaar (Moving tools)

move huge and tiny things, e.g. concentrating force tools like the hammer moves a nail, the maul moves a stake, or a whip moves flesh on a horse. These operate by applying physical compression to a surface. In the case of the screwdriver, the force is sideways and called torque. Writing implements deliver a fluid to a surface via compression to activate the ink cartridge. Also grabbing and twisting nuts and blots with pliers, a glove, a wrench, etc...) All these tools move items by some kind of force. Also Trucks, Rockets and Planes move larger items.
