Abstract
The present invention relates to a foldable knife structure, which comprises a handle; a blade pivotably conjoined to a position adjacent to one end of the said handle; a set block adjacent to the pivotable conjoinment position of the blade and the said handle, with the said set block having a detent notch; a spring situated at the other end of the said handle, with the opposite extremity of the said spring extending to a position on the said set block. When the said blade is extended from (or folded into) the said handle, the said spring is against the circumferential edge of the said set block, causing the said set block to produce torsion that rotates the said blade out of (or into) a receiving slot of the said handle, causing the said blade to automatically bound out of (or fold into) the said receiving slot.
