Any aircraft can kill you (or at the very least, embarrass you) if handled incorrectly.
things specifically to watch for on a 210:
turbulence penetration speed - do not exceed in any sort of turbulence.
forgetting to dangle the dunlops.
speeds not under control in the circuit, resulting in landing too fast and braking too hard after landing (big brakes, little tyres, very easy to blow out a main tyre or two on landing).
Remember, as aircraft age, it might not be you who is doing the incorrect handling but you might very well be the PIC who is in the wrong place at the wrong time.
However, careful pilot handling and consistently good maintenance means the well cared for 210 is a joy to fly.
(got a couple thousand hours in 210s).
to the poster who said that only the prop needs to be replaced after a prop strike - be aware the engine needs to be bulk stripped after any sort of prop strike to ensure no internal damage.
