Hello,
With damaged tiny screwdrivers it is hard to grind a new top holding them by hand. I made a little clamp th hold them on the grinder in the correct angle to achive a perfect top. I used a Aluminium sheet of 6mm thickness with 25x25 mm and drilled a 2mm hole with an offset of 4 mm to the center first and then a 6 mm hole at the center. This way you have a good hold for round shafts to hold them in place with a little screw.
I used a 3 mm thread but if not available you also can use a UNC 4-40. For the screw i choosed a length of 15 mm. The 2 round marks are 3 mm magnets for storing the tool on a steel cabinet or sheed.
best regards Guenter
