This week's Custom LEGO Weapon packs a real one-two punch. Ha! See what I did there? The Powerfists are a truly versatile item from the BrickWarriors catalog. According to one reviewer, this "snazzy attachment...can be for robots, cyber-men, hackers, steampunkers, post-apoc, just name it." We agree! Also known as gauntlets, Powerfists have been used throughout history for dozens of purposes; but the LEGO world and your imagination offer endless more possibilities. Now how about a quick lesson in historical idioms? Have you ever heard the phrase "throw down the gauntlet"? That is in reference to a medieval knight challenging another knight to duel. The challenging knight would literally throw his glove to the ground upon whence by picking it up, the challenged knight would accept the duel. So much formality! Whatever happened to just throwing punches?! Either way, the Powerfist is the perfect custom accessory to get the job done.
