Assassin's Creed IV Hidden Blade Gauntlet
Assassin's Creed fan or not, everyone needs a gauntlet with a hidden retractable blade. The Edward Kenway Black Flag replica shown here includes one that's spring-loaded with switchblade-style action. The gauntlet itself has a 3" plastic skull buckle reminiscent of the one on Edward's bandolier so everyone will know exactly which assassin showed up to the community center gym for LARP night.
The gauntlet's blade attaches to its bottom with velcro straps, and the gauntlet itself to the wearer's forearm with a strap and buckle.
I wonder if I could attach a carrot to the blade for some laughs. No wait, not a carrot, a banana. Bananas are hilarious. Also way less harmful as a weapon than both blades and carrots. Unless you hate bananas. In which case, what's wrong with you? Bananas are healthy and delicious. And banana haters better watch out because as the Bananassassin makes his rounds, he just might stop by and shove one down your throat to prove it.
