Correct screwdrivers can be found in one of two
ways, depending on the
size you need. For the small sizes, get watchmaker screwdrivers. For
larger sizes, get gunsmith screwdrivers. Both have hardened tips,
hollow ground so the point that fits in the slot of the screw has
parallel sides, not tapered sides. With those you can work those screws
without damaging them, even if they are quite tight.
Another way to find larger HG sizes is to get a (good) set of power-
drive bits that will fit a screwdriver socket handle.
Although this
has its problems with getting into tight spaces, sets of hollow-
ground hardened power bits are comparatively easy to find.
Yep, they certainly seem in plentiful supply.
re. watchmaker's screwdrivers, I've had a lot of luck with the cheap ones from
bargain stores to be honest. I bought a set many years ago in the UK, figuring
I'd buy a 'proper' set ASAP - which I never did, and the cheap set's still
going strong. Then I did the same thing in the US a few years ago, and those
too have seen a lot of use with no appreciable wear (I did kill one of the
flat-blades a while back, but that was down to user error :-)
