Askeland states that Ti alloys can have yield strengths between 170 and 1210 MPa (for 99.5% pure Ti and 13% V-11% Cr-3% Al, respectively). Austenitic stainless steels vary between about 205 MPa and 965 MPa; with precipitation hardening stainless steels can get as high as 1585 MPa. But yeah, you don't want a screwdriver as hard as a (for example) hacksaw blade -- those shatter much too easily.

Many more, I'm just to lazy. Use altavista '+dvorak +keyboard'.
This may have been said, but the HP-9000 servers at work had trayless CD drives; most DVD players, as far as I've seen, have this feature.
