Just wondering what you experienced woodworkers have learned about using cut or "square" nails. Seems they would tend to split wood near the edges worse than round nails, but I may be wrong. I know they actually hold better because the wedge aside the wood fibers, which then grip the nail like a Chinese finger puzzle. But is it always advisable to predrill when using these nails, as in, for instance, building camp boxes and cassettes? (Thanks for the heads-up Pichou.)
