You could slap a bottle opener on just about anything and make it better – a belt buckle, TV remote, baby stroller – but most of the time it’s more for a laugh than anything else. When you’re doing some real work, however, and you’ve got your toolset out, having a cold one in arm’s reach is pretty much a necessity. So, SURLY made the logical step and stuck a bottle opener onto a 15mm socket wrench to create the Jethro Tule. The 15mm box wrench is designed for use on your bike and is really a needed item for any bike enthusiast. Even if you don’t work on your bike much, it wouldn’t hurt to keep one in your toolbox cause unlike some of those random tools you never use – Why do I hav an awl? – this one can at least pop a beer.
