I used to use nail punches too! I have the green Park one now. In the shops, we've used the Var adjustable. Too $$$.
Last night, I took out a stubborn FRench fixed cup by using the Sheldon Brown tool but my socket didn't fit inside the bb. So I clamped down the fixed cup tool (Sugino) with the Sheldon Brown tool. Then I used a wood block and a hammer. Worked great.
