जेसे कि [[चाकु]], [[दराती]] ओर [[हन्सिया]], are wedge-shaped implements that produce a [[Shear stress|shearing force]] along a narrow face. Ideally, the edge of the tool needs to be [[Hardness|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 [[gouge]]s and [[drill bit]]s.

 

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.

 

include the [[ruler]], [[set square]], [[straightedge]] and [[theodolite]].

 

such as [[moulds]], [[jigs]], [[trowels]], concrete [[formwork]], [[caulk]], [[concrete]].

 

such as [[welder]]s, [[rivet gun]]s, [[nail gun]]s, [[glue gun]]s, [[glue]].
