Convex Blade:
On a Convex Blade the outside of a blade flows (rounded) into
the cutting edge without an obvious bevel. This adds strength
to the blade and cutting edge.

Corrugation:
Corrugations are small teeth on the scissors cutting edge
(one or both blades) that provide holding power to keep the
material (hair, Fabic..etc) from sliding. These are found
mostly on pet grooming or low price barber and beauty scissors.
|
Hollow Grind:
The inside of a hollow ground scissors blade, is concave or
hollowed-out. This hollow-out area produces a lined inside
edge which gives a smoother feeling cut. (Less metal to rub.)
Most finer, high quality, Barber and beauty shears are ground
this way.

Overlap:
The blades must cross one another (overlap) all the way to the
tip to perform the cutting action. |
