A forgotten tecnique for lumber framing and putting on plywood and
waferboard is to toe nail. Nails driven straight into end grain don't
hold diddly. When you angle all stud wall nails, the holding power is
much greater. The same with sheeting. If all of the nails are driven in
at the same angle, you can knock it out with your hands, and the nails
will still be in the sheet. When the nails are driven in at opposing
angles, the only way to get a sheet back off is to destroy the sheet
because the nails will pull through the sheet, and not come off with
it.
