Do you mean the same spanner and open spanner? And is the fast wrench mysterious?
A fast board is also called a ratchet board. Manual tools are more efficient.
The board generally refers to the opening spanner (in some areas of the spanner and stay open board referred to the board).
An open wrench is an adjustable wrench. The wrench has a single head (that is, one with open and double ends and two with openings).
