Section 5: Choosing a Tension
System
So now you’ve arrived at the final important determining
factor that you as a stylist must decide on when selecting the ideal shears.
Thanks to incredible engineering and technical innovations in the industry
many shears now have adjustable settings to suit personal preferences and
techniques. This section has been specially created to cover this valuable
area.

Adjustment
Screw
The oldest tension system is the adjustable screw. Some are wide slotted
and can be adjusted by a coin. Others require a screwdriver. Although
some stylist like the streamline design of a regular screw, most miss
the ease of adjustment provided by the newer more sophisticated systems.

Direct
Adjustment Knob
In an effort to make adjustment easy
for the user, manufacturers have
developed adjustment knobs or dials.
These allow the user to simply turn the adjuster with their fingers
to increase or decrease tension.

Leaf
SpringTension System
This system is found on many shears. It adds a leaf spring below the
tension dial, which spreads the tension out lengthwise in the pivot
of the shear. This system can extend the life of the edge by stabilizing
the blades causing a more evenly distributed wear pattern.

Ball
Bearing Leaf Spring Tension
Some tension systems include ball bearings which act to further stabilize
the blades. The bearing is tightly fitted in the center of the shear
and the blades rotate on the bearing instead of the typical nylon
or teflon™ washer. [Back to Top] |

Flat
Bearing Tension Systems
It is also possible to find shears with internal ball bearings or
teflon discs
between the blades. There are also some flat screws with locking detents
that click when turned. These tend to
hold tension well and can provide a stabilized flat pivot of the shear
for those who prefer a streamlined look.

Reversible
Leaf Spring Tension System
Some shears have a tension system that can be reversed
for left handed stylists. Usually right handed shears with tension knobs
are not easy to use for left handed stylists, because the knob will be in
their way when cutting scissor over comb or cutting hair held between their
fingers. On a reversible shear, the stylist can remove the knob and plate,
push out the screw (making sure the washer comes out with it) and then reinsert
the screw from the opposite side of the shear and reattach the plate and
knob. Now the knob will face their hand when they cut left handed, and will
not be in the way for the techniques mentioned above. This is ideal for
left handed stylists, who use right handed shears.
