The opener in question is, as previously mentioned, one of the more pervasive and cheaply available extruded aluminum, made in China, openers. The specific item used was a promotional keychain for QBP's FrostBike open-house (2007). The test-beers were Tyranena Brewing Company 's Bitter Woman IPA. (Caveat; the beer in question is actually a twist-off cap, which hopefully did not skew results)
First impressions were that the opener was "dinky at best", unimpressive, but pleasantly simple. Also noted were that it was discrete, incredibly average, uninspired, and (for better or worse) non-lethal {footnote 1}.
The FrostBike opener uses a traditional "pull-up" style, but has a fairly small amount of leverage. As far as opening abilities, this opener does about as well as you'd expect from looking at it. Out of six beers opened, only one was able to be opened in one pull - the rest required a secondary pull to finish them off
