"I've used forged nails on a few occasions, they work much better than both screws and wire cut nails. The trick is to place the forged nail with the widest part perpendicular to the grain of the wood. This allows the wedge shape to shear through the fiber which deflects the fiber down meaning the nail is held in place by the compressive force of the wood fiber itself. Lee Valley had an online article explaining get the properties of forged nails and why they were superior to screws and wire cut nails."
