Update
Strike one - washers too ductile.
Strike two coins too small these days and I'm not spoiling the large old fashioned Swiss Francs I found under the back seat!
Strike two and a bit - butane not hot enough (as bloody usual) => note to self about time you bought a decent propane torch you kipper.
Now searching for the original idea => 1/2" sockets with screwdriver bits much like those posted by Diesel911. Only problem most are too thin and I don't fancy my chances of grinding a curve on hardened tips...
What a bloody day - I'm fed up.
