As the craft beer industry has changed over the years, so have bottle openers. When craft breweries adopted aluminum cans over the last decade, openers evolved to include a little nub to help pick up a pull tab or puncture the tear strip. Other models now include a serrated blade to help cut through wax that many brewers use to coat caps and necks of special-release beers. Some openers are designed to keep bottle caps intact, allowing them to be reused or utilized in art projects or installed on bar tops.
While fancy or functional openers are handy, just about anything else that can be leveraged between the glass lip and crown cap will work. This includes, but is not limited to, a BIC lighter, a table or counter corner, a beer can and a wedding ring.
