I was lucky enough to snag one up from Cubicdissection's first batch. It was a very fun solve that tripped me up for several days, not to mention a beautiful piece of work! I am selling at cost to help fund my next puzzle purchase. Here is the description from the site.
Hip-Flask is Felix Ure's widely anticipated second design, following his very successful Titan take-apart puzzle. Described as a fiendishly challenging, multi-stage, sequential discovery puzzle, the goal is to remove the lid from the flask.
Machined from solid brass, Hip-Flask measures 72mm in height and weighs 750g or approximately 1.5 lbs. The brass is left unfinished, leaving it to slowly patinate and darken with use. Difficulty: 7/10
