The EXTENDING Rapier is a Real 16th Century "Trick Weapon"

The kind of "trick weapon" you would expect to see in games like Bloodborne or Assassin's Creed, except it's real, from the 16th/17th century. There is even more than one of these! A rapier that can transform between single-handed and two-handed "mode"... now isn't that like a real-life fantasy sword? It caught my eye when I visited the Royal Armouries, and I just had to dig a little deeper. Such a unique design, and impressive craftsmanship! Let's talk about how it works and whether it's a good idea.
