Awl--
They indeed exist--in both coarse and fine thread. Very handy thing to have around. Their main use, fwiu, is so that the screw tip does not poke thru
3/4" wood, etc., as happens w/ 1" screws.Very hard item to find, esp. the fine thread, but I am, after having searched high and low for nigh-on 10 years, picking up a few pounds from a very good hardware store in Mt Vernon, NY, which reluctantly ordered them for me, as now, the owner says, he will be "stuck" w/ the balance. :) He already carries the 3/4" course.
fwiw.
