 Do "they" make ordinary fluted (and fluteless too, why not) dies that
are taper at one side, and bottoming at the other (so you can start and cut
a thread easily, and by reversing the die in the holder you can tap up close
to a corner eg the head of a machine screw)?
 Silver solder/brazing resist, paint it on, solder/braze, then wash it
off, and the silver solder/braze will not wet the portion where the resist
was? Even if flux gets on it?
 Small long sub-diameter slow-helix good steel drill bits with
replaceable screw-in full diameter carbide tips?
 Hand hacksaws where the blade is screwed in place to a
wider-than-the-blade-width holder which does not twist in the frame, and
which does not rely on the blade tension and two miniscule barely flat-ish
parts to prevent the blade from twisting?
