1:1 The Hidden Blade of Ezio Life-Size Replica

This Assassin's Creed Gauntlet Replica is about as realistic as it gets. Part of Ezio Auditore's garments, it perfectly recreates the gauntlet in the Assassin's Creed series.

Aside from the beauty of the armband itself, it features spring-loaded action and a rubber-like blade. Ezio's Gauntlet comes in two separate parts: the Outer Vambrace and the Inner Wrist Guard (where the spring-loaded action resides). It comes in "one-size-fits-most," with adjustable straps to fit almost any forearm:

Wrist measures to 4 1/2 inches, forearm measures to 5 inches and outer vambrace is 10 3/4 inches.
