Our professional Hair Styling Scissors are manufactured of high-carbon stainless steel 440C AISI standard and its optimum hardness in the vacuum of an atmospheric chamber. (Typically C57-C59 on the Rockwell C-scale.)Scissors are made in three handle configurations offset, semi-offset and straight. With the offset handle, you can work with your shoulder straight and elbows down, using minimal wrist movements. The semi-offset is a comfortable compromise between the offset and straight-handle scissors.
