Its main feature is the 8 special screwdriver electronic assemblies (computers & other phones, gadgets ...: 3 star with 6 branches, one hexagon, 3 1 Phillips and classic). Each piece screwdriver is a small hexagonal room with a screwdriver at each end, which is mounted on a tip holder (ie 4 pieces). The tip can also be used Allen key (4mm). The tip may stall in 2 positions, or in the perpendicular extension of the handle.
The small pen serviced me at least once, and the pin: it does not take place and it is useful.
I use it mainly as a knife (very sharp) and I noticed that he had to be careful to wash out to dry screwdriver. The screwdriver mounted on the bit holder can slightly rust at the fixing.
It is a bit big but I can keep it permanently in my bag to hand - hard to get lighter for the number of screwdrivers available!
