This Moby looks like it wants to chow down on some bottle caps with a quickness. Wonder if the whale's stomach is big enough to hold as many caps as mine is to hold the beers they unleash.
Moby Whalers are all made by tietzj3, which is likely a pseudonym for Captain Ahab. Designs are simple by wicked, and materials vary based on tietzj3's whims for their various (and sporadic--gotta stay tuned) releases. Past openers have been made from brass, copper, titanium, and aluminum. All come with an authentication card.
