I seem to remember bottle tops in US just twist off- which threw me when confronted by a Budweiser bottle and no bottle opener.. (Until I dug out my SAK (Champ)). Normally in such dire circumstances I use the table edge to whack off the top... <img src="/ubbthreads/images/graemlins/paperbag.gif" alt="" />

But the Yard guard is much better than a table edge! (Probably, don't have one to verify that opinion, but a post with no mention of yard knives may be taboo these days... <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> )
