This is Museum Replicas’ prop replica of the Assassin’s Creed II Extension Knife.
It comes with a soft leather bracer so that it can fit securely onto the arm.
The high-carbon steel knife has a push and lock system, making it screen accurate to Ezio’s extension knife in the Assassin’s Creed II video game.
Sheathed it measures: 10″. Drawn it extends to 14″.
This knife isn’t sharpened out of the box but it can be, although if you do Museum Replicas doesn’t want to know about it and won’t honor any warranties or be held responsible for any assassination attempts you may or may not make.
Now, these are available from a variety of places, but beware – not all vendors are asking the same price. I’ve seen this for sale for hundreds of dollars difference depending on where you look.
Ebay is by and far the cheapest place to get one brand new. But, to show you the difference in ranges, here are a couple of links:
ASSASSIN’S CREED II Ezio Extension Knife with Leather Bracer (Ebay, $119)
ASSASSIN’S CREED II Ezio Extension Knife with Leather Bracer (Amazon, $290.40)
Note: The extension knife is compatible with Museum Replicas’ Assassin’s Creed II Ezio Vambrace.
