Abstract
A method of making a fishhook including the steps of stamping a paddle-shaped block from a planar section of sheet material while leaving one end of the block connected to the sheet material, forming a gap in the sheet material about the part of the block spaced from its connected end, forming a tapered portion adjacent a pointed end in the free end of the block and then bending the free end arcuately so that the block has a J-shaped configuration and then separating the block from the sheet material.
