Make your own security screwdriver trick?

good tip, thanks

A much more durable version

Hint for making three spoke screwdriver for Nintendo etc That is for the screws holding the case of Gameboys. They are like philips head screwdrivers but 3 points instead of 4 points, possibly trade name Tri-Wing screws. Start with a 2mm across flats basic Allen (Hex) key.Form the "screwdriver" on the end of the long section of the key.Hold in a pair of Mole-grips (Lock-jaw pliers).Then under a magnifying inspection lamp grind flutes into the Allen key.That is every other flat grind a flute with a thin grinding wheel or diamond/tungsten faced wheel in a Dremmel. Then open out these flutes to cut into the adjascent flats leaving just the central section to engage in the 3 screw slots. Then grind a slight chamfer on the end of each spoke to match the internal form of the screw heads. A professional job would case-harden by heating the key and dunking in Casenite (carbon rich) powder to harden the ground surface. My smallest Torx screwdriver made in similar fashion about 15 years ago is still in service without case hardening so not really necessary. This Torx driver started as a 1.5mm across flats Allen key and grinding a flute in the centre of each flat. More tips off URL below
