Meaning of side hook in English:

side hook

noun

Woodworking
  • A wooden board with a block of wood along the far edge on top, and a similar block along the near edge underneath, used to hold work steady on a workbench.

    The lower block is pressed against the bench by the operator, while the work is held against the upper block; this upper one is typically shorter than the width of the board, so that wood may be sawn right through without being obstructed by the block.
