Aviation snip also known as shears, are hand tools used to cut sheet metal and other tough webs. There are two broad categories: tinner's snips, which are similar to common scissors, and compound-action snips, which use a compound leverage handle system to increase the mechanical advantage.
Blade shears consist of two blades arranged similarly to scissors except that the hinge is at the end farthest from the point (not in the middle). The cutting edges pass each other as the shearer squeezes them together and shear the wool close to the animal's skin.
Ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing as well as engineering and building to measure distances or to rule straight lines.
Divider, instrument for measuring, transferring, or marking off distances, consisting of two straight adjustable legs hinged together and ending in sharp points. It is used principally in drafting for the accurate transfer of dimensions from a measuring scale and in machine shops for scribing lines on surfaces, usually machined, with dimensions taken from a ruler.
Pneumatic drill - a power drill powered by compressed air.
A rivet gun, also known as a pneumatic hammer is a type of tool used to drive rivets. Nearly all rivet guns are pneumatically powered. The rivet gun is used on the manufactured head side of the rivet and a bucking bar is used on the buck-tail side of the rivet. Those rivet guns used to drive rivets in structural steel are quite large while those used in aircraft assembly are easily held in one hand. A rivet gun differs from an air hammer in the precision of the driving force.
Rubber mallets are used when a softer blow is called for than that delivered by a metal hammer. They are typically used to form sheet metal, since they don't leave marks and are softer, as well as for forcing tight-fitting parts together, for shifting plasterboard into place, in upholstery, and a variety of other
