Remembering where you left the key is the hard bit. I now have 5 - due to

A couple now live on the radiators which sometimes get a bit of air in them.
One in the car for when I am at my daughter's and feel the top of the
radiators and think "mmm, needs bleeding". I think the others are in my
toolbox.


I'm still using the solid brass one that was left to me by my
grandfather in 1983. I lose it from time to time, but it always turns
up. (unlike combs, socks or biros!)


If you have radiators that often need bleeding you either have an air
leak (Oxygen into the system tends to induce corrosion) or you have
plain corrosion and it's hydrogen building up. You may want to find the
cause.
