Cheers Kirk - I remember your mod and liked it very much. Do you have the link for it please? I don't have the tools to modify the bottle opener at the moment, and I guess the problem with using the phillips is that the head is wider than the neck so unless I fit a padded collar into the adapter there will always be a certain amount of movement. I'm not concerned with a perfect fit, just to improve on the current situation.What is Prattleys?
