A nail is basically a wedge. A nail pounded in too close to the end of a board could “wedge” the wood fibers apart and result in an unsightly split. Thankfully, there’s an easy fix to this problem: Turn your wedge into a punch. Before hammering the nail through the wood, take a few seconds and pound down the tip of the nail. The blunted nail will “punch” through the wood without splitting it. Check out some more hammer tricks here.
