Hinge Handle
used to increase the length of a wrench.
Extension Bar
a type of wrench, or tightening
tool, that uses separate, removable sockets to fit
many different sizes of fittings and fasteners, most
commonly nuts and bolts. It generally includes a ratcheting mechanism that allows the
nut to be tightened or loosened with a continuous motion, rather than requiring that the
wrench be removed and refitted after each turn.

used for cutting the inside of curves or radii.
Trojan Snips
designed especially for cutting heat-treated aluminum alloy and stainless steel.

a hard steel tool that can be used for cutting and
chipping any metal softer than the chisel itself.
Round – Nose Chisel
It is used for cutting B-grooves and inside sharp angles.
Diamond-point Chisel
used to remove waste metal when a very
smooth finish is not required or when the work cannot be
easily carried out with other tools such as a hacksaw, file,
bench shears or power tools.
Flat Cold Chisel
used to remove waste metal
when a very smooth finish is not required or when
the work cannot be easily carried out with other
tools.
Single Bevel Point Chisel
is used in tiny opening in upward or
standing position.

used for general work.
Hand File
used to square ends, straighten uneven edges
and smooth rough edges.
Mill File
are parallel in width and tapered in thickness for perfectly flat filing. Double cut top and bottom with both sides safe, these a long, narrow files for precision work.
Pillar File
are parallel in thickness, tapered in width, and thin. Like a hand or flat file that comes to a point on the end. Used for flat work and slotting.
Warding File
taper in width and thickness, coming to a point, and are narrower than a standard half round. Used for filing inside of rings.
Half – Round File
are tapered in width and thickness, but the knife edge has the same thickness the whole length, with the knife edge having an arc to it. Used for slotting or wedging operations.
Knife File
is the instrument used to rule lines and the
calibrated instrument used for determining
measurement is called a measure.
Ruler
are hand tools used in the metal trades to
mark lines on workpieces, prior to machining.
Scriber
A device used to measure the distance between two symmetrically opposing sides.
Can be as simple as a compass with inward or outward-facing points and also the depths.
Calipers
also known as a measuring compass, is a mathematical, drafting or cartographic instrument used to aid measurements of the length of irregular lines and of distances on maps or charts.
