Forgot to add (wrote the original post on my iphone at night): as is it's too long to fit into the corkscrew, so using this method would require you to cut the bit in half before inserting. Had I had a spare bit, I would have done that - I find a small Phillips hear is more useful than a small flat head, simply because a small flathead can normally be traded for eithe the tip of a knife (yeah, bad I know) OR the small flathead on the can opener.
