Sewing Scissors,Types of Scissors for Sewing

Scissors
General scissors are usually less than 6 inches long and have a straight handle. They are useful during the sewing process for clipping corners of fabric, cutting excess seam allowances and evening hems. General scissors can also be known as embroidery scissors, and are frequently used in decorative needlework projects.
Shears
Shears are the largest type of general sewing scissors. They are generally 6 to 9 inches long, and have a bent handle, with one large hole for fingers and one smaller one for the thumb. This angle in the handle allows you to cut fabric while holding your hand above the table, to enable easier cutting. Shears are extremely sharp, and should only be used to cut fabric or threads to maintain their sharp edge.
Pinking shears
Pinking shears are a specialized type of shears, generally used to finish edges of fabric. They create a zigzag edge on the fabric, as opposed to a straight line. Pinked edges are less likely to ravel in a finished garment, so pinking shears are valuable in garment sewing.
Applique scissors
Applique scissors are used, naturally, in applique work. They have one regular blade and one rounded blade. The rounded blade is held against the fabric, slipping in between the layers to be cut, while the pointed blade stays above the fabric and does the cutting. The rounded blade is less likely to cut the
bottom layer, making it easier to neatly cut the applique shapes smoothly while maintaining a sharp and clean edge.
Snips
Snips are very small scissors, about the size of the palm of your hand, with blades about an inch long. They generally don't have holes for your fingers. Instead, the snip is held and squeezed to close the blades. Snips are used for cutting threads during the sewing process.
Scissors care
No matter what type of scissors you own, there are definite ways to take care of them. Never use any sewing scissors on anything except fabric or thread. Wipe down the blades, removing any thread or fabric dust, before putting them away. Also, have your scissors professionally sharpened once every year or two, whenever cutting begins to take more effort. With a little care, good scissors can last more than one lifetime.
