IKEA Japan was in the news today in a paper in Sweden. Apparently a man in Chiba had little accident when trying to assemble a chest. According to a METI's recent press release a screw broke and a piece of it hit him in the eye. Apparently the man had tried a slotted screwdriver (flathead) on a phillips (whether they really mean a phillips, or pozi, I don't know). Now, I could be wrong but the things I have bought from IKEA has a manual containing a rather big picture of a screw head with a cross on it. For me this means that one should use a crosshead driver and preferably nothing else.

So a little info on screwdrivers, link
Read it and think of the man in Chiba.
