New Scissors & Run-in Time
A: The run-in time in question is usually a matter of the stylist getting accustomed to the feel of a new pair of shears. If the shears are of good quality, are properly sharp, and are of the right size to fit the stylist's hand appropriately, then they should perform beautifully from day one.
The scissors may be "tight" because the join point/pivot point hasn't been worked much if at all. If the scissors are completely machine made and finished, the tension in the joint may be high, making them harder to open and close initially.
The scissors may come to the stylist unsharpened. It is rare, but does happen with some manufacturers (specifically if a country's laws classify scissors of any kind as a weapon). If the stylist is unaware of this, his or her first attempt to use them could be embarrassing. However, having the scissors sharpened obviously resolves this issue.
Sometimes, when scissors are packaged for sales or shipping, they may be treated with a product to protect the finish of the metal and blades from the effects of moisture. This residue is beneficial, but can affect the way the scissors perform initially. When you get new scissors, be sure to wash them carefully and sanitize them. This process (and the chemicals used) tends to remove the residue very effectively.
