4.5mm version of the tool for anyone who wants to change batteries, clean up or repair any of the following:
Sega game carts
Sega systems
Game Cube
Turbografx
SNES systems
N64 Systems
Game Gear
(and some cable tv equipment, though that is not our area of expertise)
The tools are constructed from Coated S2 Carbon Steel. This makes them INCREDIBLY durable, far better than the old silver type which were plain steel and far better than the black ones which although they look good, we found they were not durable long term.
Note: This is a hand tool, not intended for use with a power screwdriver or other uses outside the intended product uses listed.
