Blade shape: There are two types of shapes in blades, these are:
Convex blades: This blade is shaped and rounded from the outside of the scissors blade up to the edge.
Beveled blades: This is a straight plain / flat blade.

Sharpness Edges:

Convex Edge: This does not have a visible separate edge. This is a new technique in scissors edges and has a long lasting sharp cutting effect. This helps for a effortless cutting and for long period of time.
Razor Edge: This edge is done for scissors with convex shape blade. A separate edge is crafted at the end of this convex shaped blade.
Beveled Edge: This is a regular form of edge which was initially introduced. This has a slight creaking sound (two blades meet) as this is a nature of metal. Never-the less this is still considered as a very successful type of blade. This edge has an ability to cut any form of hair and this edge is heavier / thicker than other edges.


Handles:
Off-set handles: The scissors with this type of handle has two different handle sizes. Where the middle finger fits in the hole, this handle is slightly longer compared to the handle where the thumb is inserted.
Simi-Off set handles: This is more-or less similar to the off-set handles. The only difference is that the length size of the handles is slightly less difference in length.
Opposing handles: The lengths of both the handle are the same and therefore called opposing.

Screws:
Adjustable Set screw: This type of screw does not need a screw driver to adjust. This can be immediately adjusted according to need of the user. Scissors with adjustable screw are over-all more preferred, for this reason.
Premium Screw: This type of screw will only be adjusted with the help of a screw driver.
Fixed Screw: This type of screw cannot be adjusted after manufacturing; its use is negligible now.

Finger rests:

Detachable finger rest: These finger rest are screwed to the handle and can be removed by un-screwing according to need.
Fixed Fingers: These finger rest are in one form with the scissors and are shaped when the first stage of scissors forging is done. These can not be removed or detached. These can only be removed by cutting them off. These forms of finger rest's) are also called fixed finger rest.

Two piece wielded Shears:
This scissor is two piece welded by latest technology (Blade made by 440C while the handle is made by 410 stainless steel). By this technology the scissors can be save during the re-sharpening and during adjustment as 440C scissors cannot be adjusted due to very hard steel broken during adjustment by hammer. Due to the flexibility of handle, scissor adjustment is easy and clients like it very much.


TC scissors:
These types of scissors have extra strip made of materials like tungsten carbide, and cobalt, which is welded on the cutting edge. These scissors provide far longer cutting performance.
