@EventBusSubscriber(bus=Bus.MOD)
public class NoPunchWood {
	
	@SubscribeEvent
	public static void block_break(final BlockEvent.BreakEvent event)
	{
		Block blockIn = event.getState().getBlock();
		Item itemInHand = event.getPlayer().getHeldItem(event.getPlayer().getActiveHand()).getItem();
		
		if(blockIn instanceof LogBlock && !(itemInHand instanceof AxeItem))

}

Recently I tried this event to execute my code. Nothing happens when I break a block, I think its well registered. At this point is BreakEvent the old BlockBreakEvent?

I tried doing something with events lately myself and for some reason my Events Class was not properly registered when using the annotation.

Try registering it in your main mod class's constructor (the one with @Mod annotation) using:

MinecraftForge.EVENT_BUS.register(YourEventClassName.class); 

Please keep in mind that if you pass the class itself in the code above (like I have done), all your @SubscribeEvent methods must be static.

Do I still need the annotation 

@EventBusSubscriber(bus=Bus.MOD)

?

No, if you are going to register it using the EVENT_BUS, there is no need for the annotation.

This is the wrong bus for this event. You don't need to specify one for this event.
