A pair of hairdressing scissors comprising:

• a first cutting member and a second cutting member pivotally connected together, the first cutting member comprising a first handle at a first end thereof and a first blade at a second end thereof, the second cutting member comprising a second handle at a first end thereof and a second blade at a second end thereof, a through-hole being defined in at least one of the first handle and the second handle;
• and
• a connecting block securely mounted in the through-hole, the connecting block comprising a dovetail groove in a first side thereof and two dovetail blocks in a second side thereof, the first side of the connecting block further comprising two spaced transverse grooves intersecting with the dovetail groove, thereby dividing the dovetail groove into a first engaging section, a first insertion section, a second engaging section, a second insertion section, and a third engaging section in sequence;
• the dovetail blocks of the connecting block of said pair of hairdressing scissors being releasably engaged with a dovetail groove of a connecting block of a pair of similarly constructed hairdressing scissors by means of respectively inserting the dovetail blocks of said pair of hairdressing scissors into a first insertion section and a second insertion section of the connecting block of said pair of similarly constructed hairdressing scissors and then moving the dovetail blocks of the connecting block of said pair of hairdressing scissors into one of a first position and a second position, wherein when in the first position, the dovetail blocks of said pair of hairdressing scissors are respectively engaged with the first engaging section and the second engaging section of the connecting block of said pair of similarly constructed hairdressing scissors such that tips of the first blade and the second blade are aligned along a straight line and located at the same level, and wherein when in the second position, the dovetail blocks of said pair of hairdressing scissors are respectively engaged with the second engaging section and the third engaging section of the connecting block of said pair of similarly constructed hairdressing scissors such that tips of the first blade and the second blade are aligned along an inclined line and located at different levels.
